Kolkata's Netaji Subhas Chandra Bose International Airport was put on high alert on Tuesday after an unidentified man called the authorities and informed them that there was a bomb on an IndiGo flight.

According to reports, passengers of the Kolkata-Mumbai IndiGo flight No 6E5227 were taken to safety after the call was received.

 “The call came after the passengers had checked in. The flight was scheduled to take off at 1.30pm and land in Mumbai at 4.20pm. All 195 passengers were asked to deplane following emergency protocol and the aircraft was taken to the isolation bay,” an airport official told Hindustan Times requesting anonymity.

Bomb squad members are currently scanning the aircraft.

The security of the airport has been tightened.

“Luggages have been unloaded from the aircraft. Bomb squad personnel are on board. They are scanning the aircraft. The Central Industrial Security Force (CISF) personnel have tightened security all over the airport,” the official said.

Security across all Indian airports have been tightened amid recent escalation in tension between India and Pakistan.

Operation Sindoor

Operation Sindoor was a fierce military operation launched by the Indian Air Force (IAF) on May 7, in response to the Pahalgam attack that killed 26 tourists who were enjoying their vacation at Baisaran Valley, which is referred to as India's Switzerland.

The operation aimed to dismantle terrorist bases in Pakistan and Pakistan-occupied Kashmir (PoK).

Following the operation, Pakistan targeted several Indian cities with drones and missiles, which were neutralised by the Indian Armed Forces.
