New York prosecutors have filed a lawsuit against the Weinstein Company, alleging that the studio failed to protect staff from Harvey Weinstein.
The film producer is facing dozens of allegations of sexual abuse, including rape, but denies non-consensual sex.
The lawsuit alleges Mr Weinstein abused female employees and made verbal threats to kill staff members.
A lawyer for Mr Weinstein said a “fair investigation” would show that many of the allegations were without merit.
New York Attorney General Eric Schneiderman said on Sunday that he had filed the suit against the Weinstein Company, as well as Mr Weinstein and his brother Robert, who co-founded the studio.
He is seeking an unspecified sum to cover damages, plus penalties, for victims of alleged abuse by Harvey Weinstein, 65.
The document alleges that Mr Weinstein sexually harassed and abused women employed by the studio for years.
It accuses senior executives at the company, including Robert Weinstein, of failing to prevent the mistreatment of staff despite being presented with evidence.
The suit casts doubt over the sale of the Weinstein Company, which has been battling bankruptcy and is in talks with investors.
Mr Schneiderman said his investigation was continuing, but he had brought the suit out of concern that a possible sale would leave alleged victims without adequate compensation, and could benefit “perpetrators or enablers”.-BBC
