LOUISVILLE, Ky. — A prosecutor is declining to pursue a complaint filed with police by a woman embroiled in an alleged extortion attempt involving Louisville coach Rick Pitino.

Jefferson County Commonwealth's Attorney David Stengel said Wednesday the complaint is "void of credibility." The complaint was filed with the Louisville police department's sex-offense unit.

The complaint was filed by Karen Cunagin Sypher, who is facing federal charges of trying to extort Pitino.

Sypher has pleaded not guilty to trying to extort money from Pitino and lying to the FBI.
