A bomb threat call today forced Jet Airways to ground its Kathmandu-bound flight carrying 104 passengers just before it was to take off from the IGI Airport here.
Officials said the plane has been taken to the isolation bay at the IGIA and all passengers de-boarded for a through anti-sabotage check.
The call was received at the airport terminal just before the scheduled departure time of the flight 9W260 at 1325 hours, they said.
The Bomb Threat Assessment Committee (BTAC) has been activated, they said, and a final clearance for the flight is awaited.
There were 104 passengers and seven crew members on the flight.
Security is at an all-time high in view of the Republic Day celebrations tomorrow.
