London - An elderly woman is in hospital with serious injuries after she was struck by a police motorbike escort for Britain's Prince William and his wife Kate.
The Duke and Duchess of Cambridge's convoy was travelling from London to Windsor on Monday afternoon when the accident occurred.
The woman, Irene Mayor, who is in her 80s, is in a serious but stable condition, police said.
The Sun newspaper, citing witnesses, said the escort was on the wrong side of the road clearing traffic for the couple's convoy when the incident happened.
Britain's police watchdog, the Independent Office for Police Conduct, said it was investigating.
