ASPEN, Colo. (AP) -- A Colorado judge has ruled that actor Charlie Sheen must appear in person at a hearing in Aspen on allegations he threatened his wife with a knife.

Pitkin County Chief Deputy District Attorney Arnold Mordkin said Thursday the judge denied a request by the actor's lawyers that he should be allowed to participate on Feb. 8 by phone.

Mordkin says prosecutors did not take a position on the request.

Sheen was arrested in Aspen on Christmas Day on suspicion of felony menacing, domestic violence and other charges. Brooke Sheen told police he put a knife to her throat and threatened to kill her.

Sheen denies threatening his wife with a knife. Attorneys for both husband and wife say they want to try to reconcile.

The 44-year-old actor stars in "Two and a Half Men" on CBS.
