RENO, Nev. — A woman filed a lawsuit accusing Pittsburgh Steelers quarterback Ben Roethlisberger of raping her last summer in his penthouse room at a casino in Lake Tahoe during a celebrity golf tournament.

Roethlisberger's lawyer adamantly denied the allegations today.

"Ben has never sexually assaulted anyone. The timing of the lawsuit and the absence of a criminal complaint and a criminal investigation are the most compelling evidence of the absence of any criminal conduct. If an investigation is commenced, Ben will cooperate fully and Ben will be fully exonerated," David Cornwell said in a statement.

The claim seeks at least $390,000 in damages from the quarterback, who has won two Super Bowls and is one of biggest names in sports. The lawsuit also alleges hotel officials for Harrah's Lake Tahoe went to great lengths to cover up the incident.

Teresa Duffy, a spokeswoman for the sheriff's office in Douglas County, which includes part of Lake Tahoe, said no complaints were filed about such an incident either with sheriff's deputies or the district attorney's office.

The woman's lawsuit says she didn't file a criminal complaint because she feared she would be fired and expected Harrah's would side with Roethlisberger.
