The New York City hotel maid who accused former International Monetary Fund chief Dominique-Strauss Kahn of sexual assault has allegedly worked as a prostitute, the New York Post reports.

A source close to the defense investigation told the Post that the Sofitel Hotel housekeeper would have sex with male guests at the hotel for money.

"There is information... of her getting extraordinary tips," the source told the Post.

The source also said that the maid had "a lot of her expenses -- hair braiding, salon expenses -- paid for by men not related to her."

On Friday, Strauss-Kahn walked out of court free on bail after prosecutors said an extensive background investigation of the hotel housekeeper accusing him of sexual assault gave them pause.

The hotel maid accused Strauss-Kahn of chasing her through his luxury suite in May, trying to pull down her pantyhose and forcing her to perform oral sex.

Strauss-Kahn had been free on $6 million in cash and bond but under house arrest for weeks in a ritzy Manhattan loft. The charges, which include attempted rape, have not been reduced, but the move signals that prosecutors do not believe the accusations are as ironclad as they once seemed.

The Manhattan District Attorney's Office revealed that the 32-year-old woman had committed a host of minor frauds to better her life in the U.S. since arriving in the country seven years ago, including lying on immigration paperwork, cheating on her taxes, and misstating her income so she could live in an apartment reserved for the poor.

In a letter to Strauss-Kahn's lawyers, prosecutors also said she had misrepresented what she did immediately after the alleged attack by Strauss-Kahn -- instead of fleeing his luxury suite to a hallway and waiting for a supervisor, she went to clean another room and then returned to clean Strauss-Kahn's suite before reporting the encounter.

Manhattan District Attorney Cyrus Vance told reporters after the hearing that the investigation into the alleged sex assault at the Sofitel Hotel "raised concerns about the complaining witness's credibility."

"It is a great relief," Strauss-Kahn attorney William Taylor said, adding that the case underscores "how easy it is for people to be charged with serious crimes and for there to be a rush to judgment."

"It is so important in this country that people, especially the media, refrain from judgment until the facts are all in," he said.

But the accuser's attorney did not back down on the seriousness of the charges, telling reporters that Strauss-Khan's claim of consensual sex is a "lie."

"From Day One she has described a violent sexual assault that Dominique Strauss-Kahn committed against her," attorney Ken Thompson said.

"She has described that sexual assault many times, to prosecutors and to me, and she has never once changed a single thing about that encounter," he said. "The victim here may have made some mistakes, but that doesn't mean she's not a rape victim." 

He also referred to media reports that his client was involved with a drug dealer, calling them lies.

"The DA may be on the verge of abandoning the victim, but we will not abandon her. We will stand with her," Thompson said. 

Vance said his office is committed to the truth and will continue to investigate the alleged crimes rigorously.

"The vindication of the rights of sex crimes victims is among the highest priorities of this office," Vance told reporters. "We believe we have done everything to support her and maintain her privacy and keep her safe, and we will continue to do so."

Strauss-Kahn arrived at the courthouse Friday morning in a Lexus SUV and strode confidently up the granite steps with his wife, French journalist Anne Sinclair. He wore a dark gray suit, she a white jacket.

After the hearing, he walked slowly out of the courthouse with his arm on her shoulder, smiling slightly at the throng gathered outside.

His passport remained surrendered, and he will not yet be allowed to leave the country. His other attorney, Benjamin Brafman, said Strauss-Kahn would be free to travel within the United States.'s Jana Winter and the Associated Press contributed to this report.
