An IndiGo flight bound for Lucknow from Bengaluru was compelled to turn back to Kempegowda International Airport (KIA) on Tuesday after a handwritten note, containing a hijack threat, was discovered on board. Flight 6E-451 had departed from Terminal 1 of the Bengaluru airport when the incident occurred, prompting an immediate activation of safety protocols.

The threat note, found in the aircraft's toilet, explicitly stated: “This flight is going to hijack at 6.30, ignore and see the consequences.” A passenger initially spotted the message and promptly alerted the cabin crew. Subsequently, crew members also located the note, confirming the security concern.

Following the discovery, the aircraft, which was en route to Lucknow, was immediately turned around to return to Bengaluru. As per established safety procedures, a full emergency was declared at Kempegowda Airport to facilitate a swift and coordinated response upon the flight's arrival. This declaration ensures that all necessary emergency services and security personnel are on standby.

IndiGo confirmed that relevant authorities were informed without delay, in strict accordance with the airline's Standard Operating Procedures (SOP). Upon the aircraft's safe return to Bengaluru, comprehensive security procedures were initiated. These measures included thorough checks of the aircraft and its passengers to assess the credibility of the threat and ensure the safety of all individuals.

Investigations into the incident are currently underway. The airline and airport authorities are working to ascertain the origin of the note and the individual responsible for placing it on the aircraft.
