Charlie Sheen allegedly threatened wife Brooke Mueller with a knife. The “Two and a Half Men” actor was arrested on Christmas Day following an argument with the mother of his twin sons, and sources claim he pulled a weapon out on her during the row at a rented home in Aspen, Colorado.

Although Pitkin County Sheriff's Department spokeswoman Stephanie Dasaro did not provide details on what kind of weapon Sheen is accused of using, it is thought to be a knife.

Sheen, 44, was arrested on investigation of second-degree assault, a felony charge, and criminal mischief, a misdemeanor charge. He spent much of his sons’ Bob and Max's first Christmas behind bars.

He was later released on an $8,500 bail and while he was not charged, a court date has been set for February 8, 2010. Despite the domestic violence claims, Sheen and Mueller – who married in May 2008 – have no plans to divorce. Sheen's manager, Mark Burg, said: "I have spoken to all parties concerned. There are no plans for divorce. They are both deeply upset about what happened and are trying to work things out amicably.

They both want to get away from all the sensationalism surrounding what happened and quietly resolve things."

Sheen was previously married to actress Denise Richards, with whom he has two young daughters, Sam and Lola, as well as a 25-year-old daughter Cassandra from a previous relationship.
