A cop lost the file but a commuter found it and handed it to The Sun.

The shocking security blunder could have provided terrorists planning an attack with invaluable data.

A shamed senior cop has been carpeted.

The chief inspector in Scotland Yard’s Territorial Policing branch is said to be “hugely embarrassed” by the potentially serious blunder.

The dossier contained details that would have helped al-Qaeda terrorists mount a devastating attack on the Games in London this summer. “Restricted” files spell out security plans in place at the sites of events and provide minutes of top-level meetings where ways to beat terrorists were discussed.

The dossier contains dates and details of pre-Olympics rehearsals, explains emergency “lock-down” procedures and sets out plans to avoid traffic congestion.

Worryingly, names and mobile phone numbers of constables, sergeants and inspectors are included.

The dossier also reports at length on damning complaints from officers about the radios they will have to use during the Olympics.

One frustrated cop says: “Radios NEVER work properly.”

Games alert … main stadium

The documents were found by a commuter on a train in Dartford, Kent, on January 5. Realising their importance, he gave them to The Sun and we returned them to police.

The blunder is especially embarrassing because the files contain memos from senior officers stressing the importance of appearing “professional” during the Games.

The commuter said: “I couldn’t believe any policeman could have left this on a train. It’s a worry.”

The Met tried to play down the incident. saying the files were not thought to be operationally sensitive.

A spokeswoman said: “An officer lost his bag containing a number of documents. He reported the loss.

“The Directorate of Professional Standards have been informed, as is routine.”
