The Swiss Justice Ministry says it will not contest film director Roman Polanski's release on bail.

The 76-year-old will be transferred from a Swiss jail and put under house arrest in his Swiss chalet as soon as bail is posted and an electronic monitoring system has been installed, authorities said Thursday.

Polanski will also be asked to hand over all ID and travel documents — he has both French and Polish citizenship.

On Wednesday, a Federal Criminal Court agreed to grant Polanski's release on bail of $4.5 million, as long as he remains under house arrest at his Swiss home in Gstaad and is placed under electronic surveillance.

Two previous bail proposals had been rejected by the courts.

Polanski, director of Rosemary's Baby and Chinatown, has been in a Swiss jail since Sept. 26 awaiting extradition to the U.S.

He is wanted there for sentencing on a 1977 conviction of having sex with a 13-year-old girl. He fled on the eve of his sentencing in 1978 because he feared the judge would give him a sentence longer than his plea bargain.

It is expected to be several weeks before the Swiss Justice Ministry makes a decision on the U.S. request to extradite him.
