Police said that the incident took place last evening Tirah Crossing where constable Mahesh Chand was deputed to manage the traffic movement there.
"When Mahesh was handling the traffic movement, an auto driver, identified as Imran, suddenly parked his vehicle in the middle of the road and left for buying grocery items from a nearby market. His parked auto was slowing down traffic movement," said a senior police officer.
"The fight turned ugly when Imran started assaulting him and tore off Mahesh's uniform. After tearing police uniform, Imran tried to run away from the spot, but he was nabbed by some passerby and taken to police station," officer said.
He further said that based on a complaint filed by Mahesh, who suffered injuries on his head and leg in the assault, police have registered a case against Imran at Loni police station.
