Tripura Police have launched an investigation into the death of a student on the National Institute of Technology (NIT) campus near Agartala on Wednesday. Rahul Kumar, who hailed from Bihar, was found unconscious on the floor of his hostel bathroom and later declared dead when taken to the GB Pant Hospital.

The second-year student of the Tripura Engineering College’s electronics and communications department had no past complaints of any major ailment, a police officer said. “We are waiting for the post-mortem report to know the exact cause of death, but we have already begun a preliminary investigation,” he said.

According to reports, fellow students forced an entry into the bathroom after the 21-year-old student remained inside for a long time.

Rahul Kumar was found lying unconscious and taken to the GB Pant Hospital following the advice of a local doctor.

Hospital sources said no injury marks were visible on his body.
