A hoax bomb threat was made with regard to an Air Arabia flight scheduled to leave for Sharjah from the Calicut International Airport on Saturday morning, leading to the aircraft being grounded while the bomb detection squad of the police inspected it, airport sources said.

One of the passengers who arrived on the aircraft from Sharjah to Calicut had left a note saying ‘bomb’ on one of the seats and it was found by the ground staff before boarding commenced, a senior airport official said.
