Glasgow, Scotland ? Fighter jets escorted a commercial plane carrying 172 people to an airport in Scotland on Wednesday after a passenger passed the captain a note saying there was a bomb on board, and the plane landed safely.

Ryanair Flight FR25, a Boeing 737 en route from Paris to Dublin, Ireland, was escorted to Glasgow’s Prestwick Airport. No bomb was found, Strathclyde police said.

A passenger handed a note written on a page of a magazine to the pilot, which claimed a bomb had been hidden beneath a seat, Strathclyde Assistant Chief Constable John Neilson said.

Neilson said police were working to establish if the passenger had written the note or innocently discovered it.
