BJP activists engaged in a pitched battle with police on Monday after they were stopped from marching to Barrackpore police commissionerate in protest against alleged deterioration of the law and order situation in the area, officials said. Amidst chants of `Jai Shri Ram`, `Bharat Mata Ki Jai`, and `Mamata Banerjee Hai Hai`, over 500 protestors managed to breach two police barricades at Chiria More-BT Road crossing. However, their progress was halted at the third barricade after police used water cannons to disperse the crowd.

As tensions escalated, BJP protestors resorted to pelting stones, leading police to fire tear gas shells to restore order, resulting in chaos, officials added.
