The incident occurred before departure of flight 6E3074 from Kolkata, which had been scheduled to take off at 9:15 a.m. According to airport officials, crew members found a slip of paper inside the aircraft’s lavatory stating that a bomb was on board. The discovery triggered emergency protocols, and security agencies were alerted within minutes.

Airport Director confirmed that standard operating procedures were followed. The aircraft was escorted away from the main terminal area to an isolated zone to ensure passenger safety and prevent disruption to other flight operations. Bomb disposal squads and security personnel then conducted a thorough search of the plane and surrounding area.

Officials said passengers and crew were safely deboarded and taken to a secure holding area while checks were underway. There were no immediate reports of injuries or panic among travelers. Authorities have not yet confirmed whether any explosive device was found, and the investigation remains ongoing.

Preliminary inquiries suggest the note may have been planted shortly before boarding, though investigators are reviewing CCTV footage and passenger manifests to determine how it was placed inside the aircraft. Security agencies are also questioning ground staff and passengers as part of routine procedures following such threats.

Aviation experts note that isolation bays are designated secure zones at airports used specifically for handling potential threats, including bomb scares, hijack alerts, or suspicious cargo. These areas allow authorities to inspect aircraft without risking passengers, staff, or infrastructure.

The incident caused minor delays to airport operations but did not lead to widespread disruption, according to officials. Additional security checks were temporarily introduced for departing flights as a precaution.

Authorities said strict action would be taken if the threat is found to be a hoax, noting that false bomb threats are treated as serious offences under aviation security laws.

Further updates are expected once the investigation concludes and forensic analysis of the note is completed.
