Police have registered a case against several persons after a cop and another individual were injured while trying to stop a fight between two groups in Navi Mumbai, an official said on Wednesday. The incident took place on Monday near a powerhouse in the Panvel area, he said.

A police sub-inspector deployed at the powerhouse tried to pacify two groups that had got into a confrontation but he was pushed by the mob. When a second person accompanying the cop started filming it, the mob thrashed him.
