The new evidence shows staff at the Manhattan Sofitel high-fiving and doing a celebratory dance after the hotel's chief engineer, Brian Yearwood, had a meeting with Nafissatou Diallo, who claims the ex-International Monetary Fund chief tried to rape her in his hotel room, The Daily Telegraph reported.
A surveillance video taken at the hotel shows Yearwood meeting with an unidentified colleague after meeting with Diallo.
"The two men high-five each other, clap their hands and do what looks like an extraordinary dance of celebration that lasts for 3 minutes," said a report in the New York Review of Books.
The report also claims Strauss-Kahn was warned that a private e-mail of his had been sent to the Paris office of French President Nicolas Sarkozy's UMP party from his BlackBerry, after which Strauss-Kahn claimed his cellphone had been hacked.
Friday night, Douglas Wigdor, one of Diallo's attorneys, said the claims were "preposterous" and "not based on facts or evidence."
"This is like saying Neil Armstrong did not land on the moon, or that JFK [assassinated U.S. President John F. Kennedy] was shot from the grassy knoll," he told The Daily Telegraph.
