Charlie Sheen in knife threaten claim

Charlie Sheen's wife has accused the actor of threatening her with a knife during a Christmas Day argument.

The Hot Shot star was arrested on Friday in Colorado on suspicion of assault, menacing and criminal mischief against his wife Brooke Mueller, according to media reports.

A 911 call recording was released by Aspen police, and it features Mueller (Sheen's third wife) accusing the actor of threatening her with a knife before family members intervened.

She is heard saying to the emergency operator, "Right now we have people who are separating us, but I have to file the report. It's like some switch blade, he has it in his back pocket."

The argument is said to have started after Mueller claimed she wanted a divorce and custody of their eight month twin boys.

Sheen has denied claims of assault and threatening with a knife. While he admits both slapped each other on the arms, he insists the argument was "predominantly verbal".
