Mohali, April 2 -- A 22-year-old law student of Chandigarh University was brutally stabbed to death at a housing society in Gharuan in the wee hours of Wednesday. The victim, Aman Dahiya, hailed from Ghibalana village in Haryana's Sonepat district, said police. According to the victim's uncle and advocate Neel Kumar, Aman had gone to drop off a university friend at her flat around 3 am. As he stepped outside the vehicle, three youths surrounded him without provocation. Kumar alleged the trio caught hold of Aman, and stabbed him multiple times in the chest and back. Grievously injured, Aman managed to run towards a vacant plot and contacted his friends over the phone for help, identifying the assailants as Ram, Monu and Vinay. The friends rushed to his aid and took him to Government Medical College and Hospital (GMCH), Sector 32, Chandigarh. But doctors declared him dead. Aman's uncle Neel Kumar told police that he received a call from his nephew's friend around 3 am on Wednesday informing him that he had been attacked with a knife by a group of youths and was being rushed to the hospital. Kharar deputy superintendent of police (DSP) Karan Sandhu said preliminary investigation suggested the assailants believed that their names had surfaced in a previous case and suspected Aman of giving information. "This appears to be the motive behind the attack," he said. The family told police that Aman had earlier mentioned receiving repeated death threats from one Ram. Investigators said they will also be questioning the victim's female friend who was being dropped off at her flat at the time of the crime. Based on the uncle's complaint, police booked the accused under Sections 103 (murder), 126 (2) (common intention), 351 (wrongful restraint) and 3 (5) of the Bharatiya Nyaya Sanhita. One of the accused had been arrested, while raids were underway to nab the remaining suspects, said police. The post-mortem examination was held at GMCH-32 on Wednesday. Police are scrutinising CCTV footage from the area for further leads....
