Raipur: A IndiGo flight from Nagpur to Kolkata made an emergency landing here on Thursday after receiving a bomb threat which turned out to be a hoax, officials said.

A passenger was detained following the incident.

The flight with 187 passengers and six crew members on board landed at the Swami Vivekananda Airport here sometime after 9 am following the threat, Raipur Senior Superintendent of Police Santosh Singh said.

According to preliminary information, a passenger told the flight crew about the presence of a bomb when the flight was in the air.

Air Traffic Control was informed and the flight was diverted to Raipur. Upon landing, he was immediately taken to the containment bay for mandatory security checks, the police official said.

A police team and a bomb squad also arrived at the airport. All passengers were disembarked and the aircraft and passengers’ luggage were thoroughly checked, Singh said.

“After a full inspection, the bomb threat was found to be a hoax. The passenger who informed about the bomb was detained and is being interrogated,” added the policeman.

The flight departed for Kolkata around 12 noon, airport officials said.

On October 24, a similar threat was issued to an Alliance Air flight from Kolkata to Bilaspur (Chhattisgarh), following which the aircraft was checked at the Bilaspur airport, but nothing suspicious was found.
