Film director Roman Polanski has been taken into custody in Switzerland and faces extradition to the US for having sex with a 13-year-old girl in 1977.
Mr Polanski, 76, was detained on Saturday as he travelled from France to collect a lifetime achievement award at the Zurich Film Festival.
The Swiss Justice Ministry said he was being held under a 2005 international alert issued by the US government.
A spokesman said the US would now have to make a formal extradition request.
The director can contest his detention and any extradition decision in the Swiss courts, he added.
Mr Polanski's lawyer, Georges Kiejman, said he planned to challenge his client's arrest.
"We are going to try to lift the arrest warrant in Zurich," he told France Info radio. "The [extradition] convention between Switzerland and the United States is not very clearMr Polanski fled the US in 1978 after pleading guilty to unlawful sexual intercourse with an underage girl.
He was initially indicted on six counts and faced up to life in prison.
In recent years, he has tried to have the rape case dismissed, claiming the original judge, who is now dead, arranged a plea bargain but later reneged.

Earlier this year, Judge Peter Espinoza agreed there was misconduct by the judge in the original case, but said Mr Polanski must return to the US to apply for dismissal.
Mr Polanski's lawyers said he would not return to the US because he would be immediately arrested as a fugitive.
The victim at the centre of the case, Samantha Geimer, has previously asked for the charges to be dropped, saying the continued publication of details "causes harm to me, my husband and children".
She has also called the court's insistence that Mr Polanski appear in person "a cruel joke
