The car of a professor of Mahatma Gandhi College here was vandalised late on Saturday night by two unidentified persons on a motorbike at Peroorkada here.

The police said the car was parked in front of the house of S. Vijayakumar, the head of the Chemistry Department of the college. The windscreen and rear screen of the car were damaged.

The attack, the police suspect, was in retaliation for the suspension of two students from the college by a disciplinary committee of which Mr. Vijayakumar was a member.

The college has been witnessing a stand-off for the past few months between the college authorities and a student organisation, which was recently prohibited from operating on the campus by the High Court. The Peroorkada police have registered a case. Investigation is on.
