MILLEDGEVILLE, Ga. – Pittsburgh Steelers quarterback Ben Roethlisberger is being investigated in an allegation of sexual assault at a Georgia nightclub, police said Friday.

Officers said the alleged assault occurred early Friday morning in Milledgeville, about 85 miles southeast of Atlanta. The player owns a home about 30 miles to the north.

The two-time Super Bowl champion and some of his friends were seen visiting local restaurants and bars Thursday night.

Deputy Police Chief Richard Malone said the alleged victim, a 20-year-old college student, contacted a police officer after the alleged assault.

"He's been identified as being at the scene and there are allegations naming him as the perpetrator," Malone said.

Police said Roethlisberger and his attorney were cooperating with investigators. He was not in custody and has not been charged with a crime.

Separately, Roethlisberger has been sued by a woman who claims he raped her in 2008 at a Lake Tahoe hotel. He denies those allegations and has asked for counter-damages.
