Airport authorities confirmed that all passengers were safely deboarded and security checks were launched after the note was found inside the aircraft during boarding. The flight, which was set to depart from Kolkata, was moved to an isolation bay as a precautionary measure.
Threat note discovered during boarding
IndiGo flight 6E3074, scheduled to depart at 9:15 AM for Shillong in Meghalaya, was preparing for takeoff when crew members found a piece of paper inside the aircraft’s lavatory stating that a bomb was onboard.
Upon discovery of the note, the crew immediately alerted authorities and passengers were evacuated from the aircraft. According to the airport director, the aircraft was shifted to the isolation bay and a full security sweep was initiated.
