The three students of Patna College, expelled for four years for their involvement in a ragging incident, staged a protest on Friday demanding a rollback of the decision.

The suspended trio came to the college in the morning around 10.15am. They walked towards the chamber of the college principal, N.K. Choudhary, to protest the decision taken against them.

A college source said the students demonstrated in front of Choudhary’s chamber for about an hour, demanding rollback of their suspension order.

The Patna College administration on Thursday expelled the three students for their involvement in a ragging incident on September 4. Kumar Bhanu Pratap Singh, a first-year history student of the college, was allegedly tortured by them.
