Film director Roman Polanski has been released from a Swiss prison after posting bail worth three million euros.Whether he will be extradited to the US over accusations he had sex with a minor in 1977 will be decided by the Swiss Justice Department in the coming weeks. Under house arrest, Polanski has returned to his chalet in the upmarket Swiss ski resort of Gstaad. Despite the media attention, the Mayor of Gstaad said people in the village were hoping to return to everyday business. Polanski has been electronically tagged and must not leave his property at any time. More than 30 years ago he was charged in the US with rape and giving drugs and alcohol to a 13- year-old girl. He pleaded guilty to sex with a minor but fled on the eve of sentencing, fearing he would be jailed for 50 years. Polanski could appeal an extradition order, dragging the dispute out further.
