Film director Roman Polanski has been taken into custody on a 31-year-old US arrest warrant, organisers of the Zurich Film Festival said.
The organisers say Polanski was detained by police on Saturday as he arrived to attend the film festival. Zurich police could not immediately confirm the information.
Polanski fled the United States in 1978, a year after pleading guilty to unlawful sexual intercourse with a 13-year-old girl.
The festival said in a statement that Polanski had travelled to Switzerland to receive an award for his lifetime of work as a director.
