Christian Bale was arrested in London today in connection with assault charges brought against him by his mother and sister.
The incident apparently occurred in his hotel on Sunday.
The actor is currently being questioned by police.
He has yet to release a statement.
He has handed himself into police voluntarily over the mysterious domestic feud.
He went to Belgravia police station in central London earlier today and is still there, being held in custody.
When asked if Bale had been arrested, a police spokesman said "A 34-year-old man attended a central London police station this morning by appointment and was arrested in connection with an allegation of assault. He currently remains in custody."
His family is not talking.
