Actress Natassia Malthe has alleged that Harvey Weinstein raped her in a London hotel after a 2008 Bafta awards ceremony, in the latest claim of sexual assault by the disgraced movie mogul.

Following dozens of allegations of sexual harassment and assault, the Norwegian-born actress and model told a press conference in New York that she felt pressured into telling Weinstein she was staying at the Sanderson Hotel after being put on the spot.

Malthe, now 43, said after her shift as a spokeswoman for an electronics firm on Feb 10 she went back to her room and went to sleep, but was awoken by "repeated pounding" on her door, from someone yelling: "Open the door Natassia Malthe, it's Harvey Weinstein."

Feeling humiliated, she said she opened the door. She alleged Weinstein began implying sex would get her a role in an upcoming film while semi-undressed and then he began to touch himself.

"I was sitting on the bed talking to Harvey when he pushed me back and forced himself onto me. It was not consensual. He did not use a condom," she said.

"I was completely grossed out. I believe that I disassociated during the time that he was having sex with me. I laid still and closed my eyes and just wanted it to end. I was like a dead person. Afterwards I lay there in complete disgust."
