Pintu Biswas was beaten up with iron rods, bricks and bamboo sticks in the presence of several people at a puja pandal in Ashok Nagar area on Saturday night for allegedly protesting against the bursting of noisy fire crackers.
He was declared brought dead after he was rushed to the hospital following the incident.
Additional Superintendent of Police Bhaskar Mukherjee, however, said the killing seemed to be an outcome of old rivalry and the police was probing into this angle.
