Singer MARK SHAW of Eighties rockers THEN JERICO has been attacked after he popped out to run errands near his London home.
The star, 46, was beaten by a gang of teenagers in Tooting, south London - and required 15 stitches to his head following the incident.
Shaw was found to have four holes in his skulls, a broken nose and two black eyes.
He says, "It was terrifying, I was convinced I was going to die. One of them kept smashing me over the head with my metal stick while the others egged him on."
Take a look back at October's inaugural event.
The film is expected to continue without Mendes' involvement.
