Mohali/Panchkula, July 2 -- Three persons lost their lives in separate hit-and-run cases in Mohali and Panchkula on Monday. In the first case, a 27-year-old security guard, identified as Rajvinder Singh, died after a speeding car hit his motorcycle near the railway underbridge on Airport Road, Sector 82, close to IISER, around 8 am. According to police, Rajvinder was on his way to duty when a car, bearing registration number HR 68 3530, rammed into his two-wheeler. Passersby rushed him to Sohana Hospital, where doctors declared him dead on arrival. The victim's father said Rajvinder left for work around 8 am, as per his routine. "We received a call from his friend informing us that a car had hit him. His friend was present at the spot and took him to the hospital," he added. Police said the car was being driven recklessly and efforts are underway to trace the vehicle and its driver. The railway underbridge where the incident occurred is known to be an accident-prone zone. In March 2025, the same spot claimed the life of an IT worker from Uttarakhand. SHO IT City Inspector Satwinder Singh said, "The flow of traffic at the underbridge is very high, especially during morning hours when vehicles rush, which often results in accidents." In the second incident, a 26-year-old man identified as Tarlochan Singh, of Chandiala village in Derabassi, died after a crash with a tractor near Chandiala village around 8 pm. Tarlochan was on his motorcycle while his uncle was following him on a separate two-wheeler. According to the uncle, a tractor, bearing registration number PB 70 H 2400, approached at high speed and suddenly applied brakes. Tarlochan crashed into the tractor and fell. His uncle rushed him to the nearest hospital, but he succumbed to his injuries. The complainant told police that the tractor driver, who also lives in the same village, was driving recklessly at the time of the incident. Police have registered a case under Sections 281 (rash driving), 324(4) (mischief) and 106 (death by negligence) of the Bharatiya Nyaya Sanhita (BNS). In the third case, a 55-year-old home guard volunteer, Sarvesh Kumar, died as a speeding motorcycle struck him while he was crossing the Kalka-Zirakpur highway on foot.
