Teghoria: A 75-year-old man travelling on his nephew's bike was killed when the nephew rammed into a divider on VIP Road on Thursday evening, police said.

Debashish Kar, 48, and his uncle Gopal Chandra Dey were headed towards the airport when the accident occurred between Kestopur and Raghunathpur.

Kar had zigzagged his Bajaj Pulsar 150 through the traffic and sped down the VIP Road flyover like a "bullet", an officer of Baguiati police station quoted motorists as saying.

"The bike suddenly crashed into the divider between VIP Road and the service lane opposite the Big Bazaar outlet in Teghoria," he said. "Kar was speeding and he possibly lost control of the bike."

A man who runs a tea stall on the service road along VIP Road said the bike had skidded for at least 60m before it came to a stop.

"The person on the pillion was flung into the air... he landed head first on the divider and collapsed. The rider landed a few metres ahead of him," the man said.

Both Dey and Kar were wearing helmets at the time of the accident, the police said.

Some motorists took the two to a private healthcare unit on VIP Road where doctors declared Dey dead.

Kar is admitted to the hospital with injuries.

"Dey had suffered multiple head and chest injuries. He was unconscious when he was wheeled in and had lost a lot of blood... we couldn't revive him," a doctor said.
