The media executive, 63, is under investigation for allegedly groping the woman at the Tribeca Film Center. His accuser is a 22-year-old Italian model, the New York Post reported Monday.

The accuser claimed she met Weinstein after the Thursday premiere of his New York Spring Spectacular at Radio City Music Hall, where she arranged a Friday night audition at his office, according to the Post. The model claims he touched her sexually during their private meeting.

The former beauty queen also has ties to former Italian Prime Minister Silvio Berlusconi, whom she spoke out against in 2011 after attending a sex party at Berlusconi’s home, according to the Post.

“We believe this is a blackmail attempt, and he did nothing wrong,” a source close to Weinstein told the newspaper on Monday.

But the accuser’s attorney Mark Jay Heller disputed the blackmail claim, telling the Post, “There absolutely was no attempt of blackmail, and, in fact, making such a false allegation adds insult to injury, causing a duplicity of victimization.”

Weinstein has not been charged at this time, an NYPD spokesperson confirmed to PEOPLE on Tuesday.

The Oscar-winning film producer did not attend the premiere of his newest movie, Woman in Gold, at the Museum of Modern Art Monday evening. He was expected to appear alongside actresses Katie Holmes and Helen Mirren.

A representative from the New York County District Attorney’s Office declined to comment on the ongoing investigation.
