New Delhi/IBNS: In a road rage case, a 30-year-old police constable died of head injuries after a car dragged him through the road in Delhi's Nangloi area late last night.

The cop, Sandeep, was wearing civilian clothes and was out on duty to probe the reason behind the sharp rise in theft cases in the area.

The cop was on his bike when a WagonR car tried to overtake him. The four-wheeler was being driven rashly and the cop asked the driver to slow down.

Suddenly, the car's speed increased, hitting Sandeep's bike from behind. The motorcycle and the cop were dragged for about 10 metres.

He was rushed to a nearby hospital and then referred to another hospital. But the cop succumbed to his injuries.

A CCTV camera in the area showed the cop gesturing to the car driver to slow down. But the car was then seen picking up speed and hitting him.

According to police, the car had two occupants. Following the accident, the duo left the car and fled the spot. Police have seized the vehicle and are looking for the accused.

A murder case has been registered in this connection.

The cop is survived by his mother, wife, and a five-year-old son.

According to reports, one of the car's occupants was involved in the illegal liquor trade, but police have not confirmed this.
