Submitted by Subeditor on Wed, 2016-01-27 21:08 Bengaluru: A bomb threat to an Air Asia flight at the Kempegowda International Airport in Bengaluru on Wednesday turned out to be a hoax after security officials found no trace of an explosive device on the flight. There was panic among the passengers when the cleaning staff found a letter in a domestic flight which spoke of a bomb having been planted on an Air Asia flight which had landed at the KIA from Jaipur carrying around 160 passengers. The flight was scheduled to depart for Goa at 12.35am when the security personnel alerted the airport. Soon passengers checking in to the flight to Goa were frisked and their baggage checked. A bomb disposal squad and sniffer dog squad were also pressed into service. After three hours of search, the security officials declared the threat to be hoax. After securing the security clearance, the flight took off at 4.40 pm, a police officer said. Security has been tightened at all airports till Jan 30 as directed by the Bureau of Civil Aviation Security (BCAS), said a KIA spokesman.
