New Delhi: A video of passengers evacuating through emergency slides of an IndiGo flight that received a bomb threat at the Delhi aiport is going viral across social media platforms. As soon as authorities were informed about the bomb scare, they jumped into action and began the evacuation process. 

The Varanasi-bound IndiGo flight from New Delhi with 176 passengers onboard received a bomb threat on Tuesday morning but a search of the aircraft found it to be a hoax, police said.

 As the evacuation began, emergency slides were deployed at the front and rear of the aircraft, following which passengers then scrambled onto the wing via emergency doors and exited down the slides before hurrying away from the plane.

The passengers were later flown to Varanasi in another plane, around 11 am. 

"At around 5 am, an information was received regarding a paper found in the lavatory of an Indigo flight scheduled to depart for Varanasi, with the phrase "bomb @5.30'' written on it," a senior police officer said.

A thorough inspection was conducted, the officer said, adding, "No suspicious items were found. It was a hoax threat. Further investigation is underway."

The officials said the threat was found written on a piece of paper in a lavatory by the pilot when the Indigo 6E2211 flight was preparing to leave from the Indira Gandhi International Airport.

A security operation was launched after the pilot informed the control room, they added.

"All necessary protocols were followed and the aircraft was taken to a remote bay as per guidelines by airport security agencies," the IndiGo spokesperson said.

All passengers were safely evacuated via the emergency exits," the spokesperson added.
