A handwritten hijack threat note found in the lavatory of an Air India flight caused a security alert at Kolkata airport on Wednesday morning

The flight was carrying 93 passengers and five crew when the handwritten note was found in the lavatory

A handwritten hijack threat note found in the lavatory of an Air India aircraft triggered a security alert at Kolkata’s Netaji Subhas Chandra Bose International Airport on Wednesday morning, just before the plane was to take off for Mumbai.

The pilot alerted Air Traffic Control (ATC) to the threat, after which security personnel rushed to the spot. The aircraft, flight AI 772, was moved immediately to an isolation bay for a thorough security check. There were 93 passengers and five crew members on board.

Security agencies have launched an investigation into the incident, according to reports. Preliminary indications pointed to a situation involving a passenger, though this has not been confirmed.

The reports available so far do not say whether the note has been judged genuine or a hoax, whether any suspect has been identified, or if the passengers have been moved off the aircraft. They also do not carry a statement from Air India.

Threat notes left in aircraft lavatories have been a recurring problem for Indian carriers. In 2024, a note reading “BOMB THIS FLIGHT” was found on an Air India Mumbai-New York flight, which was diverted to Delhi, and another was found in the washroom of a Delhi-Vadodara Air India flight that was later declared a hoax.
