A man was found dead on a service road adjoining EM Bypass, near Salt Lake stadium Metro station and Apollo Gleneagles Hospitals, early on Monday.

The man, in his 30s, identified as Sanjeev Das, a resident of Duttabad, had injuries on his head and at the back of one of his ears.

Police said the post-mortem report was “inconclusive” as it could not be ascertained whether the injuries were homicidal or accidental in nature.

The stretch along the Bypass is frequented by walkers, motorists and pedestrians throughout the day. At night, however, the area turns deserted.

The police said a passer-by had alerted them about a person lying on the road with bleeding injuries early in the morning.

A team from Phoolbagan police station took the man to a hospital, where he was declared dead. “We are waiting for the final post-mortem report. We are not ruling out any possibility at this moment,” said a senior police officer of the eastern suburban division.

Many vehicles ply down the service road along the EM Bypass and could have caused the accident, police said. At the same time, cops were unable to rule out whether someone killed the victim and dumped his body on the stretch at night.

Cops are trying to extract footage from the closest CCTV cameras. However, a large number of CCTV cameras were damaged by Cyclone Amphan, which had struck the city in May last year, and are yet to be repaired.
