Chandigarh, Feb. 21 -- A 25-year-old student of Panjab University (PU) was killed in a hit-and-run incident near the Jayanti Majri barrier (between PGI and Mullanpur) on Thursday morning when a speeding motorcycle, allegedly being driven in a zig-zag manner, rammed into his scooter. The accused rider fled the spot without stopping to help the victim and was later arrested from a hospital. This is the fifth hit and run in the city in a month. The accused has been identified as Shyam Sunder, 25. The victim, Kulbir Singh, was a native of Alipur Patti village in Tarn Taran district of Punjab. He was a second-year BA student at PU and suffered from a disability in one leg. According to the police, the accident occurred around 9.15 am when Kulbir was going towards the India Reserve Complex on his TVS Jupiter scooter. His friend Gurjeet Singh, who works with the Chandigarh Police, was following him on a motorcycle. In his statement to the police, Gurjeet said that the biker was coming from the opposite direction at high speed and swerving across the road. He suddenly lost control and crashed head-on into Kulbir's scooter near the Jayanti Majri barrier. Due to the impact, Kulbir was thrown onto the road and suffered severe head injuries. Gurjeet, with the help of passersby, immediately rushed the injured student to Post Graduate Institute of Medical Education and Research, Sector 12, where doctors declared him brought dead. Police officials said the accused did not stop to assist the victim after the collision. Instead, he allegedly called his friends, who picked him up from the accident site and took him to Government Multi Specialty Hospital, Sector-16, for treatment. Following a search, the accused was traced and arrested from GMSH-16 hospital. His motorcycle has been seized and sent for mechanical inspection.
