Students at the National Institute of Technology at Silchar in Assam on Friday night clashed with the police during protest after the death of one of their fellow students at the college hostel, sources said. A student from Arunachal Pradesh, who was in the third semester of the electric engineering course, allegedly died by suicide after he failed exams and couldn't clear his backlog papers. He had requested the college authorities to allow him to register for the next semester, but it was reportedly turned down. The police said they had to resort to mild use of force on Friday night to disperse the agitating students after tensions in the campus escalated as the students surrounded the official residence of the registrar.
