Evidence Said to Tie Ex-I.M.F. Chief to Housekeeper

The test results were consistent with what law enforcement officials have said about the account provided by the woman, the person briefed in the matter said.

They are also consistent with what Mr. Strauss-Kahn’s lawyers have suggested would be his defense — that a sexual encounter had indeed occurred when she came to clean his room at the Sofitel New York on May 14, but that it was consensual.

Other test results, including ones on samples taken from the hotel suite’s carpet, were pending.

The results described by the person briefed on the matter represented the first forensic evidence confirming that Mr. Strauss-Kahn, 62, had indeed engaged in a sexual act with the housekeeper, a 32-year-old woman from Guinea who was granted asylum in the United States and is raising her 15-year-old daughter. The person spoke on the condition of anonymity because the results had not been released.

Mr. Strauss-Kahn, in a brief letter resigning his post last week, denied “with the greatest possible firmness all of the allegations” against him.

One of his lawyers, Benjamin Brafman, declined to comment on the test results. But in arguing for bail at Mr. Strauss-Kahn’s arraignment on May 16, he said the defense team believed “this is a very, very defensible case.”

“The forensic evidence, we believe, is not consistent with a forcible encounter,” he said.

But prosecutors contended last week that while the investigation was in its early stages, the evidence against Mr. Strauss-Kahn “is substantial” and “continues to grow every day.”

“The complainant in this case has offered a compelling and unwavering story about what occurred in the defendant’s room,” the prosecutor in the case, Artie McConnell, said. “She made immediate outcries to multiple witnesses, both to hotel staff and to police.”

The woman, he said, also picked Mr. Strauss-Kahn out of a line-up.

Mr. Strauss-Kahn — who was released on $1 million bail and a $5 million bond on Friday, essentially under house arrest in a temporary apartment just steps from Wall Street in Lower Manhattan — remained cloistered on Monday.

His original plan to take up residence in a luxury Upper East Side building upon his release from jail fell through on Friday after neighbors complained about his alleged crimes and the international news media encampment that materialized on their doorstep.

Mr. Brafman visited his client on Monday afternoon for about an hour. He did not answer reporters’ questions when he left.
