London Stansted Airport tweeted that their runway had reopened after the “precautionary” landing of Air India flight 191. The airport, located northeast of Heathrow, was briefly shut down during the emergency landing, India Today reported.
The flight was escorted by Royal Air Force fighter jets as it landed, according to BBC News. The airline originally tweeted there was a "bomb threat" but then deleted the tweet and called it a "security threat."
“We are sorry for any disruption caused by the incident and would like to thank you for your patience,” the airport said.
The nature of the threat was not specified.
The flight remained parked in an isolated part of the airport, BBC News reported.
