Three fire tenders fought for half an hour to put off the flames by the arsonists who stormed into the compound following an argument with the staff of the college over building a wall bordering the playground of a local club, a police officer said.
The mob set aflame a bike and a car parked inside the compound and also torched the computer room after forcing the staff to come out in the open.
There was no report of any injury ir any arrest in the incident.
