A DNA sample taken from Dominique Strauss-Kahn, the former IMF chief accused of sexually assaulting a hotel maid, has been matched to material found on the maid's shirt, sources familiar with the case tell NBC New York.
The 32-year-old Sofitel maid has told police that Strauss-Kahn groped her, locked her in a bedroom and forced her to perform oral sex.
Sources familiar with the case say material on her shirt matched Strauss-Kahn's DNA. Another source says DNA testing on other evidence from the scene is continuing.
Prosecutors on Thursday announced a grand jury indictment; the seven counts include attempted rape, criminal sex act, sex abuse, forcible touching and unlawful imprisonment
Defense lawyers have denied the charges and say there is no evidence of a forced encounter. They did not comment on the latest information about Strauss-Kahn's DNA.
A spokeswoman for the Manhattan district attorney declined comment.
Strauss-Khan was released from Rikers Island on $1 million bail on Friday and is under home confinement in a luxury apartment downtown.
The terms of his house arrest allow him to leave the residence for one weekly religious observance, medical appointments, meetings with lawyers and court appearances.
Prosecutors must be notified at least six hours before he goes anywhere. He also must wear an electronic monitoring device and live under video surveillance.
