Overview
- A handwritten note warning of a hijack was found in the lavatory of Air India flight AI 2772 before its scheduled departure from Kolkata, prompting the pilot to alert air traffic control on Wednesday.
- Following the alert, crew and passengers were deboarded and the Airbus A320 was moved to an isolation bay while CISF, airport police and other agencies conducted full searches under established standard operating procedures.
- After several hours of inspection the threat was declared a hoax and the flight departed in the evening at about 17:38, several hours later than its planned morning take-off.
- Airport authorities said one passenger was apprehended and handed to the NSCBI airport police after officials reported a handwriting match to the note and an alleged admission, and a criminal investigation is under way.
- The incident follows multiple similar hoax threat notes in October–November 2026 and highlights how written threats trigger time‑consuming security protocols that disrupt operations and are likely to prompt tightened airport checks and review of passenger screening procedures.
