The famed director was taken into custody by Swiss authorities trying to enter Switzerland yesterday.
Polanski pled guilty in 1977 to having unlawful sexual intercourse with a minor (she was 13) but then fled the United States before he could be sentenced. Polanski has lived in France ever since to avoid being arrested.
There has been no timeline set as to when or if he will be extradited back to the U.S.
UPDATE -- According to Sandi Gibbons, spokeswoman for the Los Angeles County district attorney's office, the U.S. Justice Department worked in conjunction with Swiss authorities in securing the arrest. According to the LA Times, they had come close to arresting Polanski several times over the past decade.
