A traffic cop in Delhi was today beaten up by a mob which accused him of physically assaulting a woman after stopping her scooter for travelling on the wrong side of the road. A traffic Inspector who had gone to the Deoli Road area to help clear congestion at 10 in the morning stopped the scooter on which three people were travelling. The woman riding it then reportedly got angry and a heated argument ensued after which she allegedly hit the cop, which snowballed into a dramatic fight.
