Actor Rhys Ifans has been accused of assaulting a guest in a hotel suite at a five-star hotel in London in the early hours of Sunday after a pre-BAFTA Awards party.

According to theatre producer Adam Spreadbury-Maher, who had been partying with a group of friends including Dominic Cooper at the Groucho club in London's Soho, claims to have seen the 44-year-old star being verbally abusive to his friend before hitting him "quite a few times" in the face.
