Christian Bale and Maggie Gyllenhaal walked the red carpet for the London premiere of The Dark Knight on Monday (July 21). Bale was lucky to be at the event because his mother and sister filed a complaint claiming the actor assaulted them at Park Lane’s Dorchester Hotel on Sunday (July 20).

When the actor went in for questioning on Tuesday (July 22) he was arrested, the police wouldn’t name Bale but did say “A 34-year-old man attended a central London police station this morning by appointment. He was arrested in connection with an allegation of assault. He currently remains in custody.”

One source told The Sun why the actor wasn’t arrested on Monday, “It was a very difficult situation but it would have been wrong to have wrecked the premiere over a complaint which we don’t yet know is founded in truth.”
