Airport operator Avinor confirmed the presence of emergency response teams at Oslo Airport after a Ryanair flight received a bomb threat.

The flight, which was en route from London to Oslo, landed safely in the Norwegian capital.

“All passengers have left the aircraft and are on their way to the terminal by bus,” Avinor press contact Cathrine Framholt told Norwegian broadcaster NRK.

Following the threat, the Ryanair flight was escorted by Danish fighter aircraft to Oslo, where it was able to land.

A British national was arrested after the aircraft landed, Norwegian police have said. A bomb unit was investigating the aircraft, NRK reported at 3pm on Friday.

“Police have the situation under control and have arrested a 51-year-old man suspected of being behind the bomb threat,” police said in a statement, adding that the suspect was British.

Police said the passengers had been evacuated off the plane, which was being examined by the bomb squad.

Denmark’s military confirmed via Twitter that two F-16 aircraft were used to escort the passenger flight.

“Danish F-16s have broken the sound barrier over Jutland with a subsequent loud bang. The planes are providing support in connection with an emergency. No further comment at this time,” the Danish armed forces tweeted just after 12:30pm.

The incident is the second threat against a Ryanair flight this week. A service from Dublin to Krakow was diverted to London Stansted Airport after a note was found in the aircraft toilet claiming a bomb was on board, media including the BBC reported.

No suspicious objects were found and two men were arrested following that incident.
