'Potter' set breached by streakers

The set of Harry Potter and the Half-Blood Prince has been invaded by a pair of streakers.

Daniel Radcliffe and Helena Bonham Carter were forced to cut short filming while security chased away the couple that ran through a woodland scene in the nude.

A source told The Sun: "Seeing naked bodies was a laugh - but the joke wore thin."

The couple returned and started making monkey noises in the background after filming resumed. The movie was being shot in Farnham, Surrey.
