Hollywood mogul Harvey Weinstein has turned himself in to police in New York, where he is expected to face sexual misconduct charges.
The charges have not been announced but US media say some may relate to accusations by actress Lucia Evans.
Dozens of women have made allegations, including of rape and sexual assault, against the 66 year old.
Weinstein has always denied non-consensual sex and this would be the first time he has been charged.
The allegations triggered the #MeToo movement which sought to demonstrate and draw attention to the widespread prevalence of sexual abuse and harassment.
What will Weinstein be charged with?
The charges will stem from an investigation made by a Manhattan grand jury. They have not been made official and the indictment depends on district attorney Cyrus Vance.
The New York Times reports that some of the charges relate to an allegation brought by Lucia Evans.
She detailed her accusations against Weinstein in an article in the New Yorker in October last year.
It is not clear if he will face more charges brought by other accusers.
It is known that New York police have been investigating allegations of rape made by actress Paz de la Huerta.
And this month Netflix producer Alexandra Canosa filed court papers in New York alleging Weinstein raped, sexually assaulted and verbally abused her over a five-year period.
The statute of limitations will be an issue in some cases but it is not thought to apply in the Evans case. Even if the limitations apply, a judge could still call women to testify to establish a pattern of behaviour, as in the recent trial of actor Bill Cosby.
The Times said Weinstein would be arraigned at Manhattan Criminal Court.
