In a statement released a few hours ago from his rep, they had the following to say:

“Christian Bale attended a London police station today, on a voluntary basis, in order to assist with an allegation that had been made against him to the police by his mother and sister,” the actor’s reps said in the statement. “Mr. Bale who denies the allegation, co-operated throughout, gave his account in full of the events in question, and has left the station without any charge being made against him by the police. At this time, there will be no further comment by Mr. Bale.”

With that said, someone (who allegedly knew someone there Sunday night, said the following (which confirms my assumption that Christian Bale’s family is trash:

“Edna: “His mom and sister are alcoholics and drug addicts, they showed up at his hotel uninvited and highly intoxicated. they were calling him big shot and that he needs to take care of his own. His mom was yelling that he would be nothing without her and he owed her. His sister was begging for money and when he was pushing her toward the door his mother came from behind and started hitting him on his head and kicking him. He managed to push them both out the door and his mom fell, they called the police and wanted him arrested. I believe that Chirstian is the victim here not his mom or sister”
Mandy: “edna, how do you know all that?”
Edna: “My father works security at the hotel, and he said it was a mess. His mom and sister wanted the front desk worker to let them into his room to wait for him. When they were told no they started cussing and yelling.  They sat in front of his door for an hour until he finally arrived.”

I’m convinced that Christian Bale would do nothing wrong.  TMZ is reporting that the “abuse” claim was verbal, not physical, which is a relief.  I can’t say I blame him for yelling at his junkie mom for trying to extort him, but that’s just me.
