The 'incident' that led to the arrest of Batman star Christian Bale was sparked by his mother insulting his wife, according to a new report.
The actor's mother and sister filed an assault allegation against him following an alleged confrontation at the Dorchester Hotel in London on Sunday.
The authorities were reluctant to speak to Bale on Monday because he was promoting his new movie, The Dark Knight, but the actor voluntarily attended a London police station yesterday.
Shortly after his release, Bale issued a statement in which he denied the assault claim and any wrongdoing.
An Insider says he lost his temper after being provoked by comments made by his mother but no physical assault took place.
"Christian was stressed, but he didn’t lay a finger on anyone,” a source tells the Daily Mail.
“Instead, he flew off the handle and cussed his mother. He just got very loud because his mother was saying some very outrageous things about him, and his wife.
"Christian's attitude is that this was his mother's fault because she became very provocative in an argument they were having,’ the source said.
"Things got out of control and he now says he wishes he just left the room.
"The thing that happened here was that normally Christian would just call a friend and go out to a pub to cool off. But he was literally trapped into this confrontation with his mother and sister because there was an army of fans and paparazzi outside."
The source adds, "His marriage is not perfect, but his relationship with his mother is in much more trouble.
"They're going to need a "cooling off" period because his mother said some pretty outrageous things to him that really set him off.
"He regrets the way she treated him in their argument a lot more than having to talk to police about it. Christian has admitted that something just snapped, but he didn't threaten anyone with violence.
2He's under a lot of pressure right now and simply got incredibly loud with members of his family around. I think his wife is going to be very important to him after all this is over because she does, at the end of the day, know how to calm him down."
As well as his strained marriage, the source claims that Bale has been deeply affected by the death of Heath Ledger, going into "hiding for the six weeks" after his The Dark Knight co-star was found dead from a drugs-overdose.
Bale was yesterday released on bail until September pending further inquiries.
