Nineteen supporters of the Communist Party of India (Marxist) and the Trinamool Congress were injured on Saturday and an office of the Left party and a shop set ablaze during a clash between the two sides and a subsequent baton charge by the police.
Trouble broke out when Trinamool supporters tried to enter the premises of a private cement factory here in a procession demanding jobs, the police said.
The police began baton-charging the processionists. The Trinamool supporters — claiming that bombs had been thrown at them by CPI(M) activists hiding in nearby shops — attacked them and assaulted a Left party member. A total of 14 Trinamool supporters and four CPI(M) activists were injured in the baton charge, the police said.
