Sylhet Kotwali police has filed a case against 150 Jatiyatabadi Chhatra Dal (JCD) men including 51 named ones on charge of vandalising vehicles and assaulting policemen during the student organisation's factional clashes on Friday night.
The clashes in Mirabazar and Upashahar areas in Sylhet city left at least 30 people including an assistant commissioner of police injured.
Police arrested 27 people, mostly JCD men, during the brawl.
At about 7:30pm, a group of JCD activists on motorbikes stormed Blessings Banquet Hall, a community centre near the Upashahar area, and fired gunshots to foil a gathering that the city unit of JCD organised to protest against the Tipaimukh project, sources said.
The attackers also vandalised 14 motorbikes and three cars in front of the community centre before leaving the scene.
Just after the incident, agitated activists from the said community centre threw bricks and stones on the house of Iftekhar Ahmed Dinar in the Upashahar area, blaming his followers for the attack.
As the rival factions engaged in chases and counter chases, police went to the scene and started baton charge. They dispersed the JCD men from Mirabazar area, where a group was preparing to bring out a procession at about 9:00pm.
The agitated JCD men put barricade on the road and vandalised a number of private cars and the official jeep of Assistant Commissioner of Sylhet Metropolitan Police Mahbub Hasan. The police official also sustained injuries at that time.
The police charged batons and arrested 27 people at Mirabazar.
Locals said a few innocent pedestrians and vendors were also caught during the incident.
The clashes occurred between the followers of city JCD Joint Secretary Iftekhar Ahmed Dinar and Siddiqur Rahman Paplu, vice-president of the same unit, sources said.
