Trinamool Congress supporters allegedly killed a student at a West Midnapore college on Friday for refusing to greet a state minister. As many as three persons have been arrested so far, reports The Indian Express.

On Friday afternoon, a group of TMC supporters reportedly entered the union room of Sabang Sajanikanta Mahavidyalaya, shouting slogans for Trinamool Chhatra Parishad, and instructed the members of Congress' student wing to greet TMC minister Soumen Mahapatra.

Some Congress Chhatra Parishad members, led by Krishna Prasad Jana (21), denied greeting Mahapatra. Following this, irked TMC supporters attacked Krishna with sticks and rods. Krishna was beaten to death in front of several other students inside the locked room. The incident was followed by massive protests across the state.

West Bengal Chief Minister Mamata Banerjee condemned the incident, but said that the Trinamool Congress Chhatra Parishad was not responsible for it. She went on to blame the Congress wing of the student union, alleging that they had locked the Principal's room.

"From what I have heard, the union room was locked from inside, while the Principal was locked in his office from outside. A clash broke out inside the union room and there was no way the Principal could get out to prevent the attackers from beating the victim," The Times of India quoted Mamata Banerjee.

The attackers had fled the scene, leaving Krishna in a critical condition. He was rushed to the hospital, where he was declared dead.

Meanwhile, state education minister Partha Chatterjee claimed the victim was an outsider, reported TOI.
