Police charged baton on BNP men to disperse them when they started noise at the end of their protest rally on Saturday noon.
The party activists also threw brick chips as the law enforcers barred them from entering Jatiya Press Club.
BNP’s International Affairs Committee member engineer Ishraq Hossain alleged that some of their leaders and activists were injured in the sudden attack carried out by the police personnel.
A chase and counter chase took place between the police and the BNP men for 15 to 20 minutes.
Later, the BNP men left the place.
