Sonu Jha (27) was beaten up by a group of boys over bursting of crackers some days ago. He died at a hospital today.
Three accused arrested for the assault had been released on bail. The mob which walked to the police station today carrying Jha's body demanded that they be re-arrested immediately on the charge of murder.
Senior police officials rushed to the scene and pacified the mob. The body has been sent for autopsy, police said, adding that further steps would be taken against the assailants.
