Los Angeles prosecutors are reviewing three accusations of sexual assault against Harvey Weinstein, a step towards possible criminal charges for the movie producer, the District Attorney's office says.
LA is one of three cities, along with New York and London, where police are investigating claims against the co-founder of the studio Miramax, who was one of the most influential men in Hollywood before more than 70 women accused him of sexual misconduct, including rape.
Weinstein, 65, has denied non-consensual sex with anyone.
"Three cases were presented to our office on February 1 by the Los Angeles Police Department regarding Mr Weinstein and are under review," Greg Risling, a spokesman for the Los Angeles District Attorney's Office, said on Thursday.
A spokeswoman for Weinstein did not immediately respond to requests for comment and a lawyer for the producer could not immediately be reached for comment.
Since last October hundreds of women have accused powerful men in business, politics and entertainment of sex abuse, joining the #MeToo social media movement that has shone a light on sexual misconduct across the US.
LA police in October said they were investigating a 2013 allegation of sexual assault against Weinstein.
The following month, District Attorney Jackie Lacey said she had assigned veteran sex crime prosecutors to a task force to look into allegations of sexual assault in Hollywood.
The New York Times in October reported on allegations of sexual misconduct by Weinstein, before LA police revealed their investigation.
