The Aspen Police Department says officers were doing a routine walk-through of the Belly Up music venue when a woman reported an assault late Friday night and named Mueller as the aggressor. Mueller, 34, was later arrested at the nightclub Escobar after midnight Saturday.
Mueller was arrested on charges of third-degree assault and felony possession of cocaine with intent to distribute.
Mueller bonded out of the Pitkin County Jail early Saturday on $11,000 bond.
Her next court appearance is Dec. 19.
