On April 1, panic ensued at Chhatrapati Shivaji Maharaj International Airport in Mumbai, India, when a tissue paper note stating 'Danger' was found in the lavatory of IndiGo Flight 911, which was preparing for takeoff to Ahmedabad. Airport authorities acted swiftly, alerting security agencies, including police and the fire brigade, due to fears of a potential bomb threat. Emergency protocols were activated, leading to the arrival of a Bomb Detection and Disposal Squad (BDDS) team, which conducted a thorough inspection of the aircraft. Fortunately, no suspicious or hazardous items were discovered, and the alert was later declared a false alarm. Authorities have registered a case against an unidentified individual to investigate the intent behind the note. Following the incident, airport operations resumed normally, with officials assuring passengers of their safety. This incident follows a similar scare at Pune Airport, where a handwritten 'bomb' message was found on another IndiGo aircraft, prompting an evacuation and investigation.
