A meritorious second-year student of Xavier Labour Relation Institute (XLRI) committed suicide in his hostel room in the institute's campus in Circuit House area, police said on Saturday.
Chandra Mohan, a resident of Chennai, had attended his classes on Friday morning but he was not found since afternoon.
When Mohan, who was among the top ten students on merit list and friendly with co-students, did not turn up for dinner, his friends went to his room and found it locked from inside, police said.
When repeated knocks on the door went unanswered, the friends broke open the door and found him hanging. He was rushed to the Tata Main Hospital, where doctors declared him brought dead.
The body has been sent for post-mortem, sources said and added that the exact cause behind the incident could not be ascertained as yet.
Meanwhile, a pall of gloom descended in the XLRI campus as it was the first such incident in the history of the institute.
XLRI has decided to call off their scheduled two-day 'Homecoming-2006', a programme for the alumni.
A condolence meeting was held on Saturday morning in the campus.
