At least three Bangladesh Chhatra League (BCL) and a Jatiyatabadi Chhatra Dal (JCD) activists were injured in clashes between them on campus on Thursday and Wednesday night.

Akhter, a JCD activist of Al Beruni hall (Ext), was beaten by Mamun and Azad, two BCL activists, inside the hall following a dispute over watching television programme at TV room at 10:30pm.

Soon after the incident, the JCD cadres, equipped with firearms, hockey sticks, rods and lethal weapons, brought out a procession inside the hall and searched for BCL activists throughout the hall. In fear of attack the BCL activists left the hall.

To avenge the attack, a group of JCD activists of Shaheed Salam Barkat (SSB) hall led by Sohel beat up Ananda and Vaskor, two BCL activists, at around 12:30am the same night.

Another group of JCD men led by AB hall general secretary of JCD Mushiur and Sijar beat up BCL activist Mintu in his room at noon yesterday. They also vandalized room no 804 of the hall.

The hall authorities formed a probe body to investigate into the incident.
