Paul McCartney had to be rescued by cops after a mob attacked his tour bus in a dodgy no-go part of Mexico City.

Youths forced his driver to stop then started jumping up and down on the roof as the Beatles legend, 67, cowered inside.

A source said: "At first his security team thought it was just swarms of fans but when people started scaling the bus, the situation changed in a flash." They called cops who raced to the rescue. "Paul and the team were shaken up," the source added.

It happened after his gig at the Foro Sol stadium on Saturday at 1am. His management team are now reviewing security.

McCartney, who was unhurt, was in Washington last night for a White House concert.
