LONDON - British prosecutors say Batman star Christian Bale will not face charges relating to an alleged assault on his mother and sister at the Dorchester Hotel on July 21.

The country's Crown Prosecution Service says there is insufficient evidence to afford a "realistic prospect of conviction" and has ordered the police not to take any further action.

British media had reported that Bale's mother and sister told police he assaulted them at the hotel a day before he attended the European premiere of his film "The Dark Knight."

Bale denies the allegation.
