The incident occurred at around 1 AM on National Highway- 24 near Akshardham temple where the victim, identified as head constable Raghu Nandan was checking vehicles along with other policemen after putting barricades on the road, said a senior police official.
"The team saw a white SUV coming from Sarai Kale Khan at a high speed. When it was signalled to stop, the driver hit Nandan and dragged him to some distance and came to a halt only after hitting the barricades," he said.
Both of them were allegedly heavily drunk at the time of the accident. Police also recovered bottles of alcohol from the car.
The head constable suffered severe head injuries in the incident and was rushed to a private hospital in east Delhi's Patparganj where he is undergoing treatment, said the official.
Kashyap was arrested and a case of rash, drunk and negligent driving was registered against him. He, however, was later released on bail.
On Thursday night, a 55-year-old Delhi Police sub- inspector was mowed down by a speeding truck in Outer Delhi's Alipur area.
