A man riding a motorbike died in an accident on Picnic Garden Road early on Thursday, police said.

Khokon Mandal, 52, was wearing a helmet when an unidentified vehicle hit his two-wheeler and sped away, the police said.

Mandal, a resident of Nonadanga’s Bhai Bhai Colony in Anandapur, was taken to the Calcutta National Medical College and Hospital, where he was declared dead.

Police officers said deserted roads or relatively less crowded stretches are more prone to accidents as vehicles tend to speed through them.

The police said they were examining footage from CCTV cameras closest to the accident spot to try and track down the offending vehicle.
