Roman Polanski remained in jail Monday, despite visits from his lawyer and a French diplomat, and it was unclear if the director had met Switzerland's demand of a full bail payment of $4.5 million to be released.

The Swiss Justice Ministry declined to say what guarantees Polanski needed to give to be transferred from the jail near Zurich to house arrest at his chalet in the luxury resort of Gstaad.

In addition to bail, the 76-year-old filmmaker must surrender his identity papers and be fitted with an electronic monitoring bracelet. He would not be allowed to leave his property as he awaits a decision on whether he will be extradited to the U.S. for having sex in 1977 with a 13-year-old girl.

"The bail must be wired to a bank account, and the bank must then notify us that it has received the bail," ministry spokesman Folco Galli said. "Nothing happens before that."

The full bail payment is standard practice in Switzerland, Galli said.

That is different from other countries such as the United States, where bail bondsmen often post a percentage of the total payment required by a court.

Polanski has been in Swiss custody since being arrested Sept. 26 on a U.S. warrant as he arrived in Zurich to receive a lifetime achievement award at a film festival. Authorities in Los Angeles want him returned to be sentenced after 31 years as a fugitive.
