Photograph: Alister Firth/Barcroft Media A plane which made an emergency landing in Scotland following security fears is back in the air, Police Scotland has said. The aircraft travelling between Egypt and the US was diverted on Saturday after a seemingly threatening note was found in a toilet. But following a search of the plane by police officers overnight, it was allowed to continue its journey on Sunday morning. "Officers from Police Scotland have carried out an extensive search of the aircraft resulting in no suspicious items being found," a spokesman for the service said. Passengers and crew are now aboard and the aircraft is continuing its flight to New York. Officers continue to investigate the circumstances of the incident. The EgyptAir Boeing 777 was escorted to Prestwick airport, Ayrshire, by Typhoons from RAF Leuchars during its flight from Cairo to JFK airport in New York. It landed at about 2.30pm on Saturday and was met by a heavy police presence. It took six hours before all 326 people on board were removed from the plane to be interviewed by police. A BBC employee, Nada Tafik, was on board the plane and said she had found a note in a toilet apparently threatening to start a fire. She told BBC News: "I'm actually the one who found the note in the rest room. When I went in to change my daughter about three hours into the flight, I found a note by the sink saying 'I set this plane on fire' with the seat number 46D written on it. So I immediately went to the crew and told them about it. It was on a hand napkin written in pencil and the pencil was actually still there so I told the crew to make sure to keep it so they can get any fingerprints off it. They locked the bathroom immediately so that no one could go into it. It almost looked like a child's handwriting or someone who has very sloppy handwriting, but it was very alarming especially these days when everyone is so concerned about safety on flights. I said to one of the stewardesses: 'I don't know if this is a prank.' They said: 'No, it can't be a prank.' Either someone has a very bad sense of humour or, you know, it's very scary. The plane was searched by officers once all passengers had disembarked. Prestwick airport is designated to deal with emergency incidents and it remained open while the EgyptAir plane sat on a runway.
