Probe into secret dossier left on road

A TOP-LEVEL police investigation was under way last night after a secret dossier containing counter-terror plans for Heathrow Airport was found abandoned on a road.

British Home Secretary David Blunkett described the disappearance of the papers, found near a petrol station close to the airport’s perimeter fence, as “very bad.”

The document, which Mr Blunkett said was genuine, was discovered by a motorist “flapping at the roadside” and handed to The Sun newspaper.
