Rose McGowan has publicly accused Hollywood producer Harvey Weinstein of raping her.
In a series of tweets, the actress also accused Amazon Studio chief Roy Price of having ignored her when she made the allegation earlier.
Amazon has put Roy Price – himself accused on October 12 of harassing a female producer – on leave of absence.
Harvey Weinstein, 65, denies any assaults. There was no comment from Roy Price.
Meanwhile, the NYPD and UK police have launched investigations into assault allegations against Harvey Weinstein. The NYPD is looking into an allegation dating from 2004 and reviewing whether there are any additional complaints. London’s Met Police has received an allegation of assault in the London area in the 1980s.
Addressing Amazon CEO Jeff Bezos on Twitter, Rose McGowan – who has appeared in Scream, The Black Dahlia and TV series Charmed – criticized the company for doing business with Harvey Weinstein.
“I told the head of your studio that HW raped me,” the actress tweeted.
“Over & over I said it. He said it hadn’t been proven. I said I was the proof.”
Twitter briefly suspended McGowan for violating its terms and policies after she included a personal phone number in tweets about abuse allegations.
Some prominent figures, notably from the entertainment world, said they would boycott the platform on October 13 in protest, using the hashtag #WomenBoycottTwitter.
Roy Price was separately accused by Isa Hackett, a producer of one of Amazon’s shows, of inappropriate behavior in a taxi and at a corporate dinner in 2015, the Hollywood Reporter writes.
Isa Hackett reported the incident to Amazon executives immediately, she was quoted as saying, and an outside investigator was brought in.
She was not told the outcome of the investigation but did not see Roy Price again at any events involving her shows, she added.
In a statement, Amazon said: “Roy Price is on leave of absence effective immediately. We are reviewing our options for the projects we have with The Weinstein Co.”
Three women earlier accused Harvey Weinstein of rape in an investigative article in The New Yorker magazine.
They are Italian actress and director Asia Argento, former aspiring actress Lucia Evans and a third woman who was anonymous.
The same article says 10 other women told the author that Harvey Weinstein had either harassed or assaulted them between the 1990s and 2015.
The New York Times broke the story on October 5, when it detailed decades of allegations of l harassment against Harvey Weinstein.
The producer has insisted through a spokeswoman that any contacts he had were consensual.
Director Oliver Stone has said he believes that Harvey Weinstein should not be judged prematurely.
“If he broke the law it will come out,” he told reporters on a visit to South Korea for a film festival.
“I believe that a man shouldn’t be condemned by a vigilante system.”
In a subsequent social media post, however, Oliver Stone expressed a wish to “recuse” himself from a TV series about Guantanamo Bay “as long as The Weinstein Company is involved”.
Oliver Stone wrote on Facebook that he was “appalled” by the allegations made against Harvey Weinstein and “commend[ed] the courage of the women who’ve stepped forward”.
