Source: Sheen's Domestic Dispute Weapon in Question Revealed

Reports claim that a knife was present during the actor's Christmas day scuffle

And the plot thickens.

As we exclusively reported Saturday, a source close to Charlie Sheen's Christmas day scuffle in Colorado revealed that a "weapon of some sort," had been involved. Now the same source tells E! News the weapon present in Sheen's domestic dispute, and the cause of his felony menacing charges, was a knife.

During the reported domestic dispute between Sheen and wife Brooke Mueller, the Two and a Half Men star allegedly threatened his better half with a knife in the living room of her Aspen rental home.

Aspen's Chief Deputy District Attorney Arnold Mordkin tells E! News that he "cannot confirm nor deny" the presence of the knife, while Pitkin County Police Department spokeswoman Stephanie Dasaro would only say that additional information regarding the Sheen case will be made available on Monday.

Calls for comment from the actor's rep have yet to be returned.
