Two men riding an app-based commercial motorbike died after the two-wheeler skidded and a Calcutta Municipal Corporation (CMC) garbage dumper hit them near the Park Circus seven-point crossing on Monday afternoon.

Police said the pillion rider, Nabin Jhunjhunwala, 39, a resident of Gariahat Road, had hired the two-wheeler from an app-bike service. The rider has been identified as Chandan Yadav, 32.

They were travelling from Ballygunge Phari towards Park Street when the accident happened at the crossing of Jannagar Road and Park Street, near the Park Circus seven-point crossing, around 12.40pm.

Eyewitnesses told The Telegraph that the bike had lost balance and faltered along the tram line before skidding. The duo fell on the road.

“Trailing the bike was a CMC garbage dumper which ran over the biker and hit the pillion rider, too,” said a police officer.

Jhunjhunwala and Yadav were taken to the Calcutta National Medical College and Hospital, where Yadav was declared dead, the police said.

Jhunjhunwala died of injuries sometime later. Both were wearing helmets.

The garbage dumper has been seized by the police.
