DCP East Zone, Gurgaon, Maheshwar Dayal said, Dr Ajit Kumar was on way to his hospital from Sohna Road, when the ASI Shamsher Singh asked the driver to stop.
Police officials alleged that the three bouncers came out of the car and began bashing up the traffic inspector, and all the while, the doctor was sitting inside his car.
Dr Ajit Kumar, however, denied he was present inside the car. He even claimed the BMW car belonged to his son.
The three bouncers are absconding, while the doctor was detained for interrogation. A case has been registered against the doctor and his three bouncers.
