At 6:30 am on Thursday, June 25, 2026, the Delhi-Gurgaon Expressway was already thick with the heavy, high-speed transit of interstate commuters. Sarthak Mattoo, a 33-year-old event management professional, was riding his black Pulsar motorcycle along the highway. He was commuting from his home in DLF Phase 4, Gurugram, to an event assignment in Noida. He wore a premium, high-quality helmet bought for him by his father, who had extracted a solemn promise that he would never ride without it.

Sarthak was riding ahead of his colleagues, who followed in two cars. He had returned to India from London with a Master's degree, recently completed his probation at the Gurugram-based event startup ENOUT, and was only two days away from celebrating his 34th birthday.

As Sarthak reached the Rajokri flyover, a critical high-speed transit point on the border of Delhi and Haryana, a speeding Mahindra Thar registered in Karnataka rammed his motorcycle from behind. The SUV made an abrupt, aggressive lane change, clipping Sarthak’s motorcycle and causing him to lose control. Sarthak skidded onto the tarmac and fell directly under the wheels of the heavy utility vehicle, which ran over him before speeding away into the morning haze. The occupants of the Thar did not stop to help the dying young man, leaving him crushed on the road.

The death of Sarthak Mattoo is not merely a story of individual tragedy, but a stark illustration of the deep fissures in India’s urban road infrastructure, the systemic failures in police forensics, and the suspended state of the country's new hit-and-run legal framework.

Chronological Investigation of the Crash and Surrounding Legal/Administrative Events

The path leading to Sarthak Mattoo’s fatal crash and its complicated aftermath is a chronicle of intersecting timelines, municipal priorities, and structural failures. Reconstructing this sequence from late June 2026 back to the start of 2024 reveals a systemic gap between public safety rhetoric and highway reality.

On Sunday, June 28, 2026, two starkly different administrative and forensic operations unfolded across the country. In Delhi, newly sworn-in Chief Minister Rekha Gupta actively enforced a municipal safety crackdown, issuing a strict video message that established a one-month deadline for coaching centers to comply with mandatory fire safety norms under threat of immediate sealing. Hundreds of kilometers away in Pune, the rural police were conducting a highly advanced forensic reconstruction at Lohagad Fort. Using a weighted dummy matching the physical profile of 26-year-old murder victim Ketan Agarwal, experts physically simulated his fall to prove he had been pushed to his death by his fiancée, Siya Goyal, and her co-conspirator. The contrast highlighted a deep disparity in forensic resource mobilization: while high-tech physical and digital simulations were deployed for domestic-homicide investigations, fatal highway collisions on Delhi’s key expressways remained subject to standard, slow-moving procedures.

The grief of Sarthak’s family culminated on Saturday, June 27, 2026—the day he would have celebrated his 34th birthday. Instead, his family lit his funeral pyre. On this day, the suspected driver, 30-year-old software tester Apurv Singh, was arrested and taken to Safdarjung Hospital for a delayed medical examination and blood-alcohol test. Holding Sarthak's sturdy, scratched helmet, his father, Surender Mattoo, made an emotional appeal to Prime Minister Narendra Modi, Union Home Minister Amit Shah, and Delhi CM Rekha Gupta for justice. Sarthak's father publicly questioned the police's delay of 50 hours in conducting the driver’s blood-alcohol test, pointing out that any chemical trace of alcohol would have cleared by then. While the police asserted that the test was conducted immediately upon the driver’s apprehension, the delay in tracing and arresting the suspects remained a point of severe contention.

The groundwork for the arrest began on Friday, June 26, 2026, as investigators mapped out the suspects' escape path. By analyzing regional CCTV highway networks, Delhi Police traced the Mahindra Thar’s route immediately after the crash. Multiple cameras placed the vehicle in the Chittaranjan Park (CR Park) area of south Delhi hours after the collision, proving that the occupants had actively fled deep into the city instead of stopping to assist the dying rider. This CCTV mapping confirmed the hit-and-run nature of the offense and allowed police to track and seize the corporate-leased SUV.

The tragedy itself unfolded in the early morning hours of Thursday, June 25, 2026, on the Rajokri flyover. Sarthak Mattoo, a 33-year-old event manager at ENOUT, set out at 6:30 am on his black Pulsar motorcycle from his home in DLF Phase 4, Gurugram, heading to an assignment in Noida. As Sarthak reached the flyover, a speeding, Karnataka-registered Mahindra Thar driven by Apurv Singh made a dangerous lane change and collided with him from behind. Sarthak fell and was crushed under the SUV's wheels as it accelerated away. A passerby discovered him critically injured, used Sarthak’s fingerprint to unlock his phone, and alerted his workplace, prompting colleague Akash Deep Choudhary to call back at 6:45 am. Sarthak was rushed to the Indian Spinal Injuries Centre by PCR personnel but was declared dead on arrival, resulting in a tragic failure of the "Golden Hour". Later that day, police traced the SUV and detained Sagar Saha, the corporate lessee, who claimed Singh was driving while he sat in the passenger seat.

The administrative environment surrounding the crash had been defined by a focus on urban fire safety. On Monday, June 22, 2026, CM Rekha Gupta met with families affected by the Saidulajab building collapse of May 30 and the Hauz Rani fire of June 3, distributing ₹10 lakh in ex-gratia compensation to each family and promising strict safety inspections. Simultaneously, a commercial fire in Aliganj, Lucknow, claimed 15 lives, prompting a citywide safety audit of Delhi’s coaching hubs and the drafting of a new regulatory safety law. This intense focus on building inspections highlighted a governance gap where road transit safety remained neglected.

A week prior to the crash, another high-profile case began to unfold. On Thursday, June 18, 2026, 26-year-old Pune businessman Ketan Agarwal fell to his death from a 400-foot cliff at Lohagad Fort near Pune. His fiancée, 20-year-old Siya Goyal, initially claimed it was a tragic accident, asserting that Ketan had slipped while posing for a photograph. While local police initially registered an accidental death report, a subsequent deep-dive investigation into their digital footprints and phone call history would eventually expose a calculated murder plot orchestrated by Siya and her lover, Chetan Chaudhary.

The systemic danger of the Rajokri flyover as an unaddressed black spot was proven weeks earlier. Early on Sunday, June 8, 2026, a speeding Toyota Innova driven by a property dealer rammed a cargo tempo on the same carriageway, overturning the three-wheeled vehicle and killing 47-year-old passenger Kripa Devi while injuring six others. The collision underscored the urgent need for physical speed-calming measures and lane segregation on the highway, which had been left unaddressed, paving the way for Sarthak’s fatal crash at the exact same location.

The broader political context was set on Thursday, February 20, 2025, when Rekha Gupta was sworn in as the 9th Chief Minister of Delhi at Ramlila Maidan, ending nearly three decades of BJP’s absence from power in the national capital. Her administration placed a high priority on infrastructure audits and citizen welfare, although these structural safety drives had yet to extend to the city’s high-speed expressway corridors.

Underpinning the legal status of the hit-and-run was the formal implementation of the Bharatiya Nyaya Sanhita (BNS) on July 1, 2024, which replaced the colonial-era Indian Penal Code (IPC). Under Section 106 of the BNS, negligent vehicular deaths were split into two distinct tiers: Section 106(1) for drivers who reported the incident (punishable by up to 5 years and a fine) and Section 106(2) for those who fled the scene (punishable by up to 10 years and a fine).

However, the legal teeth of the new hit-and-run provisions had been removed long before the crash. On January 2, 2024, the Ministry of Home Affairs suspended the implementation of BNS Section 106(2) after massive, nationwide protests and strikes by truck drivers and transport unions. This suspension remained active into 2026, ensuring that fleeing drivers could only be booked under the bailable, 5-year maximum of Section 106(1)—creating a loophole that removed the primary legal incentive for drivers to stay and save lives during the Golden Hour.

Reconstructing the Night of the Crash and the Golden Hour

The physical mechanics of the collision on June 25, 2026, reveal a sequence of reckless driving. Sarthak Mattoo was riding his black Pulsar motorcycle within the designated lanes of the Rajokri flyover. The Mahindra Thar, bearing a Karnataka registration plate, was being driven at high speed by Apurv Singh, a 30-year-old software tester residing in Gurugram. Seated in the front passenger seat was Sagar Saha, a 29-year-old colleague to whom the vehicle had been corporate-leased by a Bengaluru-based firm.

According to forensic mapping and initial findings by the Delhi Police, the Thar made a sudden, aggressive lane change on the highway. This maneuver cut directly across Sarthak’s path, leaving him no room to brake or swerve. The left flank of the SUV struck the motorcycle, causing the bike to crash onto the right side of the flyover. The momentum of the impact threw Sarthak under the rear wheels of the Thar, which ran over his lower torso and legs before accelerating away from the scene.

                                                                  |
                                                                  v
[Thar Flees Scene] <--- [Runs Over Rider] <--- [Rider Thrown Under Wheels]

What followed was a critical failure to render aid during the "Golden Hour"—the first 60 minutes after a traumatic injury when prompt medical treatment has the highest likelihood of preventing death. Akash Deep Choudhary, the co-founder of Sarthak’s employer, ENOUT, was among the first to receive news of the crash.

A passerby discovered Sarthak lying critically injured on the flyover. The passerby used Sarthak’s fingerprint to unlock his phone and called his last-dialed contact, who was one of Sarthak's office colleagues. The colleague immediately alerted Choudhary, who called the passerby back at 6:45 am. Choudhary recalls the chilling description provided by the caller: "The man told me Sarthak was in very bad shape... Both his legs were crushed and dangling from the waist".

Choudhary contacted the Police Control Room (PCR) personnel who were transporting Sarthak. Upon learning that the police intended to take Sarthak to the public Safdarjung Hospital—located further away—Choudhary urged them to divert to the nearest private facility, the Indian Spinal Injuries Centre (ISIC) in Vasant Kunj, to save precious minutes. Despite these efforts, by the time Choudhary and Sarthak's colleagues arrived at the hospital, doctors had declared Sarthak dead on arrival. He had bled to death on the tarmac and in the back of the transport vehicle.

Conflicting Accounts and the Anatomy of Flight

In the aftermath of the crash, the actions of suspects Apurv Singh and Sagar Saha highlighted a pattern of evasion. After running over Sarthak, the occupants of the Thar did not stop to render assistance or contact emergency services. Instead, they fled the scene, with highway CCTV cameras later capturing the vehicle maneuvering through Chittaranjan (CR) Park in South Delhi—miles away from the crash site—before going into hiding.

During police questioning, a significant contradiction emerged between the physical evidence and the suspects' testimonies. When Sagar Saha was detained on June 25, he claimed that his friend, Apurv Singh, was test-driving the corporate-leased SUV from Gurugram to the Dwarka Expressway and back. Both Saha and Singh later asserted a joint account of the collision, claiming they had already overtaken Sarthak's motorcycle when the bike struck their vehicle from behind, causing Sarthak to fall.

This version of events is directly contradicted by the physical evidence and witness testimonies. Eye-witness reports and preliminary findings by the Delhi Police indicate that the Thar was driving aggressively, changing lanes at high speed before cutting sharply across the Pulsar's path. The impact occurred on the left side of the SUV, indicating Sarthak was cut off from the front-right. Furthermore, Sarthak's father, Surender Mattoo, pointed out that even if a simple collision had occurred, the moral and legal obligation of the suspects was to stop and transport Sarthak to a hospital. Running over the rider and fleeing the scene suggests an attempt to escape immediate breathalyzer testing and legal accountability.

Delayed Blood Testing and the Forensic Math of Ethanol

A key point of contention for Sarthak Mattoo's family is the delayed forensic response by the Delhi Police. Although the fatal crash occurred at 6:30 am on Thursday, June 25, 2026, the driver, Apurv Singh, was not arrested and subjected to a medical examination at Safdarjung Hospital until the afternoon of Saturday, June 27—a delay of approximately 45 to 50 hours.

Surender Mattoo questioned this delay, noting that any biological evidence of alcohol impairment would have cleared from the suspect's system over those two days. This concern is grounded in the established science of ethanol metabolism, which can be modeled using a linear elimination rate:

The rate of alcohol elimination from the bloodstream can be approximated using the equation:

BAC(t) = BAC₀ − β × t

where BAC(t) is the blood alcohol concentration after time t (in hours), BAC₀ is the initial blood alcohol concentration at the time of the crash, and β represents the average ethanol elimination rate of approximately 0.015 g/dL per hour. Assuming a driver had a BAC of 0.15 g/dL at the time of the collision, the expected clearance time would be:

t_clearance = 0.15 ÷ 0.015 = 10 hours

Therefore, a blood sample collected 45 to 50 hours after the crash would not be expected to contain measurable ethanol, making retrospective proof of intoxication extremely difficult.

By the time Apurv Singh's blood was drawn 45 to 50 hours later, any trace of ethanol would have metabolized, making it impossible to prove active impairment.

While DCP Amit Goel defended the police by stating that "specialised tests still exist to test for presence of trade amounts", forensic toxicologists note that tests for trace metabolites like Ethyl Glucuronide (EtG) in urine or hair only establish past consumption, not active impairment at the time of the crash. This delay limited the prosecution’s ability to charge the suspects with more severe offenses, such as culpable homicide not amounting to murder.

Two Worlds in June 2026: Lohagad Fort vs. Rajokri

The investigative challenges in Sarthak Mattoo's hit-and-run case stand in stark contrast to another high-profile investigation that unfolded in India during the same week of June 2026. On June 18, 2026, Pune-based realtor Ketan Agarwal fell to his death from a 400-foot cliff at Lohagad Fort near Pune. His fiancée, 20-year-old Siya Goyal, initially reported the incident as a tragic accident, claiming Ketan slipped while taking photos or handing her a water bottle.

However, Pune Rural Police mobilized significant forensic and investigative resources to probe the case. Their efforts revealed a complex murder plot:

• Call Detail Analysis: Investigators analyzed call records and found that Siya and her co-conspirator, Chetan Chaudhary, had exchanged 2,004 calls totaling 238 hours of conversation over the preceding six months.

• Digital Footprint Recovery: Police recovered deleted WhatsApp messages and search history from the suspects' phones, revealing queries on "how to commit a murder" and plans to wear a disguise.

• Physical Scene Reconstruction: On June 28, 2026, forensic teams took Siya to Lohagad Fort and used a weighted dummy matching Ketan's weight to physically reconstruct the fall, proving he was pushed.

• Thermal Anomalies: CCTV footage showed Chetan Chaudhary trailing the couple at the fort wearing a heavy hoodie in 33-degree Celsius heat, which investigators identified as a deliberate attempt to conceal his identity.

LOHAGAD FORT CONSPIRACY CASE                               RAJOKRI FLYOVER HIT-AND-RUN
- Comprehensive forensic reconstruction                      - Delayed blood draw (45 to 50 hours)
- Thousands of call records mapped                           - No physical scene reconstruction
- Digital evidence recovered from devices                    - Suspects booked under bailable terms
- Dummy drop matching victim's weight                        - Road black spot left unaddressed

While the state mobilized comprehensive forensic reconstructions, mapped over 4,400 call records, and recovered deleted digital evidence to solve the Lohagad Fort murder plot, Sarthak Mattoo's case was plagued by a 45 to 50-hour delay in blood alcohol draws, booking under bailable terms, and a complete lack of physical scene reconstruction on a highway black spot that had been repeatedly neglected. This discrepancy suggests that highway fatalities are often treated as routine traffic accidents rather than crimes requiring rigorous forensic investigation.

The Statutory Sieve: The Non-Enforcement of BNS Section 106(2)

The legal handling of Sarthak Mattoo's case was also affected by the ongoing suspension of India's new hit-and-run law. When the Bharatiya Nyaya Sanhita (BNS) was introduced to replace the IPC, Section 106 was designed to address the high rate of fatal hit-and-runs, which account for over 50,000 deaths annually in India.

The new framework divided vehicular negligence into two distinct tiers:

• Section 106(1): Applies if a driver accidentally causes death through negligence but remains at the scene or reports the incident immediately. This offense is bailable and carries a maximum punishment of 5 years in prison.

• Section 106(2): Applies if a driver causes death through negligent driving and flees the scene without reporting it soon after. This offense is non-bailable and carries a maximum punishment of 10 years in prison.

However, following nationwide protests by truck drivers and transport unions, the Ministry of Home Affairs suspended the enforcement of Section 106(2) in early 2024. This suspension remained in place through mid-2026.

As a result, even though Apurv Singh rammed Sarthak Mattoo and fled the scene, police registered the case under Section 106(1). This allowed the driver to secure bail shortly after his arrest, leaving Sarthak's family to face a lengthy and unequal legal battle.

The Socio-Political Environment in Delhi

The tragedy occurred during a period of transition and high administrative activity for Delhi's municipal and state governance. Following the return of the Bharatiya Janata Party (BJP) to power in the capital after nearly three decades, Chief Minister Rekha Gupta took office in February 2025. Her administration has focused heavily on public safety and structural audits, though these efforts have primarily targeted other sectors.

In late June 2026, CM Rekha Gupta issued a strict one-month deadline for coaching centers across Delhi to comply with mandatory fire and safety norms, threatening immediate closure and sealing for non-compliant facilities. This administrative push followed a series of commercial fires, including a tragic building collapse in Saidulajab and a fire in Hauz Rani, for which the Chief Minister personally distributed ex-gratia compensation of ₹10 lakh per family and promised systemic safety laws.

Yet, this proactive approach on building safety stands in stark contrast to the persistent neglect of highway safety. Despite appeals from Sarthak's father to Chief Minister Rekha Gupta, Union Home Minister Amit Shah, and Prime Minister Narendra Modi, there has been no systemic intervention to address the hazards of the Delhi-Gurgaon expressway.

The physical neglect of the corridor is evidenced by its history of collisions. Just weeks prior to Sarthak’s death, on June 8, 2026, a speeding Toyota Innova driven by a local property dealer crashed into a cargo tempo on the same Rajokri flyover, killing 47-year-old Kripa Devi and injuring six others. The recurrence of fatal accidents at this location highlights the lack of structural speed-calming measures and lane segregation on one of India's busiest transit routes.

Systemic Failures and Necessary Reforms

The investigation into Sarthak Mattoo's death reveals a combination of infrastructure neglect, forensic delays, and legislative gaps that undermine road safety in India. Addressing these issues requires a coordinated approach across multiple areas:

• Infrastructure Upgrades: High-speed corridors like the Delhi-Gurgaon Expressway must be redesigned to protect vulnerable road users. This includes installing speed-calming measures, physical barriers to segregate slow-moving traffic, and automated speed cameras on known black spots like the Rajokri flyover.

• Forensic Standardization: To prevent the loss of critical chemical evidence, police guidelines should mandate immediate breathalyzer and blood-alcohol testing for all drivers involved in fatal collisions, minimizing the delays that often compromise prosecutions.

• Legislative Resolution: The legal impasse surrounding Section 106(2) of the BNS must be resolved. Enforcing strict penalties for fleeing a crash is critical to encouraging drivers to stay and help, protecting the injured during the vital "Golden Hour" when lives can still be saved.

Without these systemic reforms, India's highway network will remain highly dangerous for commuters. For Sarthak Mattoo's family, the current system has failed to provide accountability. As his father, Surender Mattoo, observed: "This was not merely a collision or an accident. It was a hit-and-run, a deliberate act of killing a young man under the wheels of a Thar... I simply request that you ensure I get justice".
