A woman accused of playing a role in a brutal sexual assault was arrested after an anonymous tip, according to the Anchorage Police Department.

The search for 22-year-old Mariya Kalinina lasted a couple weeks, but in the end APD found her after someone notified police of her location via Anchorage Crime Stoppers.

"APD appreciates the help from its citizens in making our community safer by reporting crime and suspicious activity to police," department spokesperson Jennifer Castro wrote in a release.

Kalinina is charged with first-degree sexual assault for alleged involvement in an August 11 incident at Arctic Tern Inn that police say followed a disagreement over heroin.

25-year-old Casey Jones and 24-year-old Lydell Butler also face charges. Both have pleaded not guilty, and Kalinina is scheduled to appear in court Wednesday.
