A 38-year-old man working with a food delivery service was killed after a car driven by a Delhi Police constable rammed his motorcycle in Rohini on Saturday night, the police said.
The suspect, Julie Singh was drunk at the duty.
“We will know for sure once we receive his medical report,” said Pranav Tayal, deputy commissioner of police (Rohini).
Singh, who serves at the Budh Vihar police station, was formally arrested from the accident spot but has been hospitalised after suffering injuries himself.
“He has been booked for causing death due to negligence and rash driving,” Tayal said.
The accident took place on the service road near D Mall in Rohini. The car also went on to hit a DTC bus.
Vijay Kumar, the bus driver, told the police that the car first hit the motorcycle and then crashed into the bus. The accident left the motorcycle mangled.
Police learnt of the incident when Tripathi was rushed to Baba Saheb Ambedkar Hospital, where he was declared dead on arrival.
The police then visited the accident site to find Singh sitting at a nearby bus stand, where he was arrested.
