A Delhi-Kolkata Air India flight, AI-020, returned to the Delhi airport after a bomb threat call was received by the national carrier's call centre.

The passengers have de-boarded and a security check is underway.

Last year on November 8, a Delhi to Kolkata GoAir flight, G8 127, had made an emergency landing at the Kolkata airport after a card with a bomb threat was spotted.
