Investigators have found matching DNA of former IMF Managing Director Dominique Strauss-Kahn with the clothes of the hotel maid who accused him of attempted rape.

Strauss-Kahn faces sexual assault charges over the alleged attack on the 32-year-old maid at the Sofitel hotel in New York earlier this month.
He denies all charges and is currently on bail at a New York safe house. On Monday, his lawyer Benjamin Brafman said that his client would not plead guilty and he was confident Strauss-Kahn would go free.

Neither the police nor his lawyers have commented on the latest reports.

Experts say that the evidence could prove there was a sexual encounter, but not that there was violence of any kind.

In a letter to the IMF staff that circulated on Monday, Strauss-Kahn strongly denied charges against him and called the events around his arrest a personal nightmare. He apologized for the pain he has caused the organization and said he was confident he would eventually be acquitted.

I deny in the strongest possible terms the allegations which I now face; I am confident that the truth will come out and I will be exonerated, he said in the letter. 

The letter reflects on his arrival at the fund in 2007 and explains his reasoning behind his resignation on Wednesday.
