"One of the accused persons went to purchase some articles from a nearby shop, while another one was seated inside the car. When Mr Gupta asked the person in the car to park the vehicle at the next shop, where they were shopping, they started a heated argument," a senior police officer said.
The argument soon turned nasty. "As some local shopkeepers started gathering at the spot, both the accused tried to flee. In the process, their car first hit a bike and then crushed Mr Gupta under its wheels when he tried to stop them," the officer added.
Mr Gupta, a resident of Karala village in Delhi's Rohini Sector 22 was taken to a nearby private hospital where he was declared brought dead.
The police has started an investigation to identify the two men in the car. "We are examining the CCTV footage of the nearby shops to ascertain the identity of the accused persons who managed to flee the spot," the police officer added.
Mr Gupta used to run his restaurant on the ground floor of his residence.
