Detectives in New York City and London are taking a fresh look into sexual assault allegations against Harvey Weinstein now that some 30 women have accused the Hollywood film producer of inappropriate conduct.
New York Police Department spokesman Peter Donald said on Thursday that investigators are reviewing police files to see if anyone else reported being assaulted or harassed by him.
So far, no filed complaints have been found, he said, other than one well-known case that prompted an investigation in 2015, but authorities are encouraging anyone with information on Weinstein to contact the department.
London police were also looking into a claim it had received from the Merseyside force in northwest England, British media reported Thursday. Merseyside police said the allegation was made a day earlier and concerned "an alleged sexual assault in the London area in the 1980s."
Some 30 women - including actresses Angelina Jolie, Ashley Judd and Gwyneth Paltrow - have now spoken out to say Weinstein had sexually harassed or sexually assaulted them. Rose McGowan, who has long suggested that Weinstein sexually assaulted her, tweeted on Thursday that "HW raped me."
The initials were an apparent reference to Weinstein, and The Hollywood Reporter said the actress had confirmed she was referring to the disgraced film mogul. The New York Times earlier reported that Weinstein paid a financial settlement of $US100,000 ($A127,820) to McGowan in 1997 over an incident in a hotel room at the Sundance Film Festival.
"Any allegations of non-consensual sex are unequivocally denied by Mr. Weinstein," Weinstein's representative Sallie Hofmeister said Thursday.
Weinstein was sacked on Sunday by The Weinstein Co., a studio he co-founded with his brother.
Some of the allegations involved conduct at hotels in Beverly Hills, but police there didn't return calls on whether they were investigating any possible crimes.
Detectives in the NYPD's special victims unit have been told to identify and speak with any potential victims, including the women who spoke about their encounters with Weinstein in a recent New Yorker article, a law enforcement official told The Associated Press.
In The New Yorker expose, a former actress, Lucia Evans, said Weinstein forced her to perform oral sex in 2004 when she was a college student.
At least one other unnamed woman said she was raped by Weinstein, but the article did not disclose when or where it happened. A third woman, actress Asia Argento, told the magazine that Weinstein forcibly performed oral sex on her in 1997 at a hotel in France.
Weinstein, through a spokeswoman, has denied any nonconsensual sexual conduct with any women.
The media mogul has long been a major figure at the Academy Awards, where his films have regularly won Oscars.
He reappeared briefly on Wednesday outside a Los Angeles home, telling the paparazzi he's "not doing OK," but he's hoping for a "second chance," according to video posted by celebrity website TMZ. He also told the photographers he needs to "get help" and "we all make mistakes."
Actress Kate Beckinsale has also recounted she was 17 when Weinstein greeted her in his bathrobe. Years later, Beckinsale said, she met Weinstein again and he asked if he had tried anything at their first meeting. She said she realised "he couldn't remember if he had assaulted me or not."
Hachette Book Group has also "terminated" Weinstein Books.
