Director Roman Polanski (pictured) will not be released on bail before the end of this week, according to the Swiss justice ministry.
The 76-year old director was granted $4.5m (€3m) bail last week on condition that wears an electronic tag and returns to his home in Gstaad.
It was thought that he would be freed last week but the Swiss Federal Justice Minstry has said that he will not leave prison before Friday as the bail has yet to be posted. It is expected to be paid within the next couple of days.
Polanski was arrested on September 26 en route to the Zurich Film Festival, where he was due to collect a lifetime achievement award. He had been held pending a ruling on his extradition to the US, after he fled the country in 1978 after admitting to unlawful sex with a minor.
