Three students of Vabni Vihar, post graduate wing of the university had been seriously injured in a clash over admission to the institute's Gopabandhu hostel last night.
After the clash the students had set on fire three motorbikes and damaged eight others in the campus, police said.
The students called off their road blockade after the police assured them of arresting the culprits by tonight. But the protest led to hundreds of vehicles being stranded on NH 5, which pass through the city.
