Semyon Varlamov, NHL goalie, arrested on kidnapping and assault charges related to domestic violence

(CBS/AP) DENVER - Colorado Avalanche goalie Semyon Varlamov has been charged with kidnapping and third-degree assault related to what authorities are calling a domestic violence incident.

Police released few details about the case Wednesday night during a brief press conference and declined to elaborate, other than to say it involved someone with whom the Russian was in an intimate relationship.

Sgt. Steve Warneke said Varlamov turned himself in to police Wednesday at about 6 p.m. local time.

The Avalanche said in a statement they were aware of the allegations but wouldn't comment further until the conclusion of the investigation. Varlamov practiced with the team earlier in the day.

Varlamov was still in custody Wednesday night, and was due in court for his first court appearance at 10 a.m. Thursday, according to the Denver County sheriff's website.

The Denver Post reports that according to Colorado statutes, Varlamov's kidnapping charge is a Class 4 felony that is punishable by two to six years in prison.

Acquired from Washington in a 2011 trade, Varlamov has seven wins in eight games this season with a 1.76 goals-against average. On Sunday night, he made 24 saves in a 3-2 home victory over Winnipeg.

The Avalanche play at Dallas on Friday night and Varlamov was scheduled to start.
