His neighbours rushed him to the Regional Institute of Medical Sciences here but he could not be saved.
The gunmen who came in a car managed to escape, said the police, who have registered a case. Officials said there were indications that the students might resort to an agitation.
In another incident in Tengnoupal district, a tribal farmer, T. Angshan, who was abducted on Thursday morning by two masked men, was found dead.
The kidnappers had said they wanted to speak to the 36-year-old farmer but his bullet-ridden body was recovered on Friday.
Activists said the farmer could not have offended any underground organisation and demanded the killers' arrest. Police have registered a case but no arrest has been made so far.
