Security experts in Switzerland have begun to prepare Roman Polanski’s chalet in the Alps for the Chinatown director’s house arrest, which may begin as soon as Monday, the Associated Press is reporting. Polanski has been in Swiss custody for the past two months while authorities there consider extraditing him to the U.S. The director fled America in 1978 after pleading guilty to a charge of unlawful sexual intercourse.

UPDATE: Reuters reports that the French envoy preparing the house say Polanski might not be released for a few days.
