Teenage Michael Caine was hit on head with glass bottle in London

Sir Michael Caine has revealed that a ruffian struck him on the back of his head with a glass bottle when he was a teenager living in London.

The Get Carter star, who visited the British capital for filming new movie Harry Brown, still carries the scar caused by the unprovoked attack.

"I remember once when I was 16, someone hit me over the head with a bottle. I didn't know he was behind me and I've still got the scar," the Daily Express quoted him as saying.

In Harry Brown Caine plays the role of a widower seeking revenge for the death of a friend.
