Roman Polanski will spend at least another night in jail.

Sources in Switzerland tell me that Polanski is not being released today from Winterthur prison.

The 76-year-old Academy Award-winning director of “The Pianist”  remains behind bars until his estate in Gstaad is approved for his home sentence. Wire reports claim that workers have been preparing the property for his arrival.

Observers wondered today if Polanski would be transferred home after his lawyer visited him at the prison. But insiders say it may yet take a couple of days before everything is worked out.
