Dominique Strauss-Kahn Accuser: 'I Know What He Did To Me'

July 25, 2011— -- In an exclusive broadcast interview with ABC News, the hotel maid who has accused former International Monetary Fund chief Dominique Strauss-Kahn of sexually assaulting her in a New York City hotel room recounted the alleged attack and responded to questions about her credibility.

"I know what he did to me," Nafissatou Diallo, 32, told ABC's Robin Roberts.

In never-before-heard detail, the maid re-enacted moments from the alleged assault, at one point kneeling on the floor to describe how she said Strauss-Kahn forced her to perform oral sex in Room 2806 at the Sofitel Hotel in New York City May 14.

When she first went to clean the room, she said, a room service employee told her the guests had checked out and the room was empty so she went in to clean the room. Still, she said, she moved from room to room in the large suite, which included an office and a living room, calling "housekeeping" to no response. It wasn't until she was walking down the hallway to the bedroom, she said, that she saw him.

"I saw a little man come to me. He come naked," she said. "I was like, 'Oh, my God. I'm so sorry. I'm so sorry.' It was so fast. ... I turned my head, he comes to me and grab my breast: 'No, you don't have to be sorry.' I said, 'Stop. Stop. I don't want to lose my job.'"

Diallo said Frenchman Strauss-Kahn, who has denied the allegations, then pulled her into the bedroom, closed the door and continued to push her toward the bed.

"I was like, 'Stop. Don't do this,'" she said. "When I say, 'I don't want to lose my job,' he say, 'You're not going to lose your job,'" and he say, 'You're beautiful.'"

"He's trying to put his penis in my mouth and I closed my lips," she continued. "I turn my head ... and I get up. He keeps pushing me everywhere ... then I was like, 'I want to kill him. I want him to stop.'"

Diallo, who's from the French-speaking West African country of Guinea, said she tried to escape as Strauss-Kahn forced her into the bathroom off the hallway.

"I had a -- my uniform is a dress -- we have, I have a dress on," she said. "He pulls up my dress up. ... I tried to pull my dress back ... he put his hand between my legs. He grabbed me so hard. I pulled his hand off."

During the scuffle in the bathroom, Diallo said, she was pushed to the floor and then forced up against the wall, injuring her left shoulder, which she said now needs surgery.

"That was time he forced his penis into my mouth," she said. "I cannot move. I cannot move. I tried. I tried to push him. ... I cannot even breathe that much.

"He said, 'Suck my d***.' I cannot say nothing," she said. "Then he back off ... I was splitting ... and I run out of the room."

Moments later, Diallo said, she went into the exterior hallway outside of the room, where she kept spitting and thought she was going to be sick. It was there that, she said, she saw Strauss-Kahn going to the elevator with his luggage.
