Mumbai:: Passengers on a Singapore Airlines (SIA) flight were stranded at Mumbai airport for more than 8 hours after a bomb threat on Sep 7 night, according to Indian media reports.
Local media quoted officials as saying that the Air India call centre in Thane received a phone call about a bomb on the aircraft and passed that information on to the authorities.
After a "complete sanitation operation" by the Central Industrial Security Force team, the threat was eventually declared a hoax, the daily newspaper reported on Saturday, adding that efforts to identify the person behind the hoax call are ongoing.
An SIA spokesperson confirmed that SQ423, which was scheduled to depart Mumbai for Singapore at 11.40pm local time on Friday (2.10am on Saturday, Singapore time), was delayed over a "security concern".
The Airbus A380 aircraft eventually departed Mumbai at about 7.50am local time on Saturday and landed in Singapore just before 4pm.
There were 328 passengers and 25 crew members on board.
