The facility, which is home to the Royal Logistics Corps, is currently being investigated by Surrey Police following the death of four young recruits.

The documents were discovered by a man out running near the base in Camberley, Surrey.

According to the Daily Mirror newspaper, they included orders for the guards and copies of security passes.

Terry Henderson Found dossier

The dossier was marked "restricted" and was found 300 metres from the perimeter fence, the paper reports.

Jogger Terry Henderson discovered the laminated paper spread across a lane close to the Princess Royal barracks last Friday night.

"It is as though someone wanted a passer-by to find the folder and is trying to say something," he told the paper.

Investigations into the deaths of the four soldiers, who all died from gunshot wounds at the barracks, have been reopened by police.

Jim Collinson, 17, from Perth, died from gunshot wounds earlier this year.

Inquiry

Private Geoff Gray, 17, from Seaham, County Durham, was found with two gunshot wounds to his head in September 2001.

And in 1995, the body of Private Cheryl James, 18, from Llangollen, north Wales, was discovered with a single bullet wound to the head.

The parents of the Deepcut victims have demanded a public inquiry into the deaths.

They reject suggestions that the four young soldiers committed suicide using their own rifles, and have accused the Army of a cover-up.

The families lobbied Westminster last week, joined by other parents whose children died while serving in the Army in a non-combat situation.

Surrey Police has confirmed that an item of lost property was handed in, and said it had since been returned to the military.
