A Kolkata-Mumbai Air India flight was placed under a security alert on Wednesday after a handwritten note warning of a possible hijacking was found on board before take-off.
According to reports, the pilot informed Air Traffic Control (ATC) after discovering the threatening message. Following the alert, airport authorities offloaded all passengers from the aircraft as a precautionary measure.
The aircraft was subsequently moved to an isolation bay for detailed security checks. Security teams began the required procedures to examine the threat and ensure passenger safety.
Further details about the note, the person who may have written it and the outcome of the security checks are awaited.
This incident comes just days after a similar hijack threat was reported on an IndiGo flight operating from Bengaluru to Lucknow.
On November 7, 2026, the Bengaluru-Lucknow IndiGo flight 6E-451 returned to Bengaluru after crew members found a handwritten hijack threat inside the aircraft’s washroom. The pilots followed standard safety procedures and informed the relevant authorities.
An earlier incident was also reported at Kolkata airport in October, when a message reading “Bomb inside aircraft” was found written on the lavatory mirror of a flight arriving from Phuket.
The latest incident has once again raised concerns over security threats involving commercial flights. Authorities are expected to provide further information after completing their checks.
