Four to five persons have been injured in a clash between two rival groups of Jatiyatabadi Sramik Karmachari Union, as affiliate of BNP, at Nagar Bhaban, the headquarters of Dhaka South City Corporation (DSCC).
A police official at Shahbagh Police Station said the incident happened around 12:00 noon on Tuesday.
The people who suffered injuries in the attacks were said to be anti-Ishraque faction and sympathetic to the National Citizen Party (NCP) and Awami League.
He said the clash took place following an altercation.
But the reason behind the altercation is yet to be determined, he added.
Asked, he said none has filed a complaint in this connection so far.
"Police will investigate the matter once a formal complaint is lodged."
General Secretary of Jatiyatabadi Sramik Karmachari Union Arifuzzsman Prince said in the last two days several city corporation employees were barred from entering Nagar Bhaban and even they were threatened with physical assault.
He also alleged they were subject to extortion by Arif Chowdhury, president of another workers' faction and his supporters.
"When we tried to resolve the issue and enter the building, we were attacked by Arif Chowdhury, a section of city corporation employees and some outsiders," he claimed.
He said city corporation employees, Md Zakir, Naushad Islam, Ariful Islam, Md Mintu, Suman Mallick and several others were assaulted during the attacks.
However, Arif Chowdhury could not be reached for comments on the matter.
