Chris Evans, the former Top Gear host, will face no action over allegations that he sexually assaulted a former colleague, the Metropolitan Police confirmed today.

A woman told Heat Street, the news website, that Evans had grabbed her breasts in the early 1990s, when he was presenting the Big Breakfast, the Channel 4 show.

It is understood that the BBC presenter - who has always denied the claims - was questioned by officers from the Metropolitan Police's Sexual Offences, Exploitation and Child Abuse Command earlier today.
