D.C. police are investigating an allegation that Washington Redskins defensive lineman Albert Haynesworth sexually assaulted a waitress in a D.C. hotel over the weekend, a source within the department said Monday.

Haynesworth's agent, Chad Speck, confirmed that his client was the subject of the complaint but denied the 29-year-old defensive tackle is guilty of any wrongdoing.

"There seems to be no truth to these allegations," Speck said in an e-mail. "We are currently evaluating facts and considering our own legal action against those involved."

When reached for comment, Redskins senior vice president Tony Wyllie said, "This is the first I have heard about this. We are gathering further information."

According to the police report, a waitress at the W Hotel stated that her hands were full as she cleared a table Haynesworth was sitting at around 1:30 a.m. Sunday.

The report said Haynesworth, identified as Subject 1, tried to give the waitress his credit card and asked if he could place it in her blouse. The waitress nodded, and Haynesworth placed the card into her blouse and began caressing her breast, the report says.

While Haynesworth is not named in the report, the police department source, who spoke on condition of anonymity, confirmed that Subject 1 referred to the Redskins lineman. The report, which was filed at 5:15 a.m. Sunday, describes the suspect as a "heavy/fat/stocky" black male with a goatee, and about 6 feet 6 or 6 feet 7.

Charges have yet to be filed, as the investigation is ongoing, police said. The allegation was first reported Monday by WRC Channel 4.

The accusation is the latest negative development for Haynesworth, whom the Redskins suspended without pay for the final four games of the season in December, citing conduct detrimental to the team.

On Saturday, he was formally charged with assault in connection with an alleged road rage incident that took place on the Fairfax County Parkway in Reston on Feb. 2. A driver accused Haynesworth of hitting him while he was sitting in his car. Haynesworth was scheduled to appear in court on March 31.

At the completion of his suspension, Haynesworth reported to Redskins Park on Jan. 3 to take a mandatory physical, but he refused to meet with Coach Mike Shanahan.

The Redskins are expected to try to trade Haynesworth if a new Collective Bargaining Agreement is reached between NFL owners and the NFL Players Association.

The current agreement expires March 4.

The Redskins signed Haynesworth to a record $100 million contract in February 2009.

Banks still in hospital

Redskins kick/punt returner Brandon Banks remained hospitalized for "precautionary reasons" Monday, his agent said in a statement. The agent, James Gould, said he expected Banks to be released on Tuesday.

On Sunday Gould said Banks would be released that night. It was unclear why Banks has yet to be released.

Banks suffered what Gould described as superficial knife wounds during a Saturday morning attack outside a D.C. nightclub that also hospitalized a good friend of Banks.

Wyllie said team doctors have been to see Banks at the hospital and reported that he was doing fine.
