The clash erupted as the JCD faction loyal to RU JCD Convener Masudur Rahman attacked a police camp on the campus while chasing opponent faction member Anwar Hossain Nipu around 4:30pm.

Earlier in the morning, JCD followers of Golam Kabir beat up Masud over formation of the Bangabandhu Hall committee.

Masud's supporters chased Nipu to retaliate the attack on their leader, but Nipu took shelter at the police camp.

As the law enforcers prevented them from capturing Nipu, the JCD cadres led by Miron and Romel attacked them.

The policemen called for reinforcement who charged baton to fight back the JCD activists equipped with brickbats and iron rods.

Later, the JCD men assaulted RU Proctor Prof Enamul Haque and damaged his vehicle for allowing the police to set up the camp on the campus.

During the clash, the police beat up Ali Asgar Khokon, RU correspondent of the Daily Janata, mercilessly. He was admitted to Rajshahi Medical College and Hospital (RMCH).

Injured policemen--Rana Sarkar, Masud Rana, Abdur Razzak-1 and Abdur Razzak-2--were admitted to police hospital.

The injured JCD cadres--Masudur Rahman, JCD members Anis Ferdous Ratul, Mahmudul Hasan Miron, Nazmul Alam Bony, Hamidul Islam, Nipu and Shankar--were admitted to RMCH and shown arrested in a case for attacking the police.
