FIVE passengers on an Egyptian aircraft diverted to a Scottish airport over an apparent threat to destroy the plane are seeking asylum in the UK.

The chief executive of EgyptAir, Tawfeek Asi, speaking from Cairo, identified the five as Syrians.

It is believed they have been transferred to London. Reports from the Middle East suggest they are suspected of planning the diversion.

The aircraft travelling between Cairo and New York was diverted to Glasgow Prestwick Airport, South Ayrshire, at around 2.30pm on Saturday after a scrawled note saying: "I'll set this plane on fire," was found in a toilet.

Prestwick is designated to deal with emergency incidents and remained open while the plane sat on a runway. The aircraft was escorted to the airport by Typhoons from RAF Leuchars.

Police Scotland confirmed the UK Border Force is dealing with the five.

The Boeing 777 was grounded for 13 hours. It was searched by police, but no suspicious items were found. All passengers were interviewed after they disembarked.

The remaining 326 passengers continued on their journey to JFK Airport at 3am yesterday after EgyptAir received permission from the Egyptian Aviation Authority to extend the crew's operating hours.

Dallia Abdel Moniem, a correspondent for Africa Review who was on the flight and headed for Boston via New York, said: "Whoever put that note in the bathroom on the Egyptair flight – thanks a million. Hoax or not you're a worthless piece."

She said passengers were left on the plane for four hours before being taken off to be interviewed.

Glasgow Prestwick chief executive Iain Cochrane said: "It was a complex and constantly evolving matter and I want to thank my staff for their unswerving professionalism and commitment during the 13 hours the aircraft was here, and praise the excellent manner in which all agencies involved worked together to resolve the matter. We have also learned some useful lessons."

The Home Office refused to comment.
