Guwahati, Nov. 11 -- A hijack threat note found in the washroom of a Mumbai-bound Air India flight at Kolkata airport on Wednesday triggered security protocols and prompted officials to move the aircraft to an isolation bay before take-off.

The flight was scheduled to depart at 10.20 am. The note, discovered shortly before departure, threatened that the aircraft would be hijacked at 11.10 am, Kolkata airport director Vikram Singh said.

All passengers who had boarded the aircraft were deboarded, and the plane was moved to the airport's isolation bay for a thorough security inspection and other precautionary measures, Singh said.

Security protocols were immediately activated following the discovery of the note.
