The clash occurred following the arrest of ISF legislator Naushad Siddiqui.

Police resorted to lathi charge and lobbed tear gas shells to disperse the crowd.

“At least 17 persons, including Siddiqui, were arrested. Police had to use mild force and fire tear gas shells to bring situations under control,” Vineet Goyal, Kolkata police commissioner, told Hindustan Times.

“Around 19 police personnel, including three senior Indian Police Service (IPS) officers, were injured,” he added.
