A teenager riding pillion on a motorcycle was hit by a vehicle after being flung on the road when an app cab driver opened his door and the two-wheeler banged against it, police said.

The accident occurred in front of Arsalan restaurant at the Park Circus seven- point crossing on Monday evening.

The 14-year-old boy, Abu Jan, was admitted to Calcutta National Medical College and Hospital soon after the accident. He died of injuries on Tuesday morning, the police said.

His brother who was riding the motorcycle escaped with minor injuries. Both were wearing helmets at the time of the accident, the police said.

The app cab driver and the driver of the other vehicle, a four-wheeler, have been arrested on charges of causing death by negligence and rash and negligent driving.

A traffic police officer said cops could not access any CCTV footage because the cameras installed on the spot were damaged by Cyclone Amphan that ravaged the city May 20.

The cameras are still to be restored, the officer said.

The driver of the other four-wheeler has apparently claimed he was not involved in the accident and that the vehicle had not touched the boy.

He was already lying on the road when the vehicle was moving on the stretch, the driver has apparently told cops.

All three vehicles — the motorcycle, the app cab and the other four-wheeler — will undergo a mechanical examination to ascertain the nature of collision between the three, the police said.

“The motor collision report will help the police ascertain the exact nature of the collision. Had the CCTV cameras on the stretch worked, our job would have been easier,” an officer of Beniapukur police station said.
