A motorcyclist was injured on the Parama flyover on Monday evening by a glass-laced kite string.

Ashok Chakraborty, 55, a correctional services official, was headed towards the Alipore special jail quarters when the accident occurred on the AJC Bose flyover ramp that connects it to the Parama flyover, police said.

He was admitted to the ENT department of SSKM Hospital.

Officers of Shakespeare Sarani police station have started a case under Section 337 of the IPC (causing hurt by the act of endangering life or personal safety of others) based on his complaint.

“It is difficult to trace the origin of a kite string. Someone flying a kite several kilometres from the flyover can cause injuries to motorcyclists. So, we have been requesting people living in high-rises close to the flyover not to fly kites,” an officer said.

There have been several accidents in the past where motorcyclists have been injured by glass-laced kite strings on the flyover.
