A first year student of architecture at the Indian Institute of Technology, Kharagpur was found hanging from the ceiling of his hostel room.
Police said they broke into the room at the Madan Mohan Malaviyya hostel in the campus and recovered the body of Manoj Kumar (18) after the hostel cleaning staff complained of a stench emanating from it.
IIT sources said Kumar, hailing from Rajasthan's Shivpuri, had preferred to stay back in the hostel even as most of the other residents have gone home for the summer vacations.
Police said prima facie it appeared to be a case of suicide and investigations were on.
Last year a fifth year student of M.Sc (Physics) had also allegedly committed suicide in the campus, the sources added.
