PARIS — A French lawyer for director Roman Polanski, imprisoned in Switzerland, says a new bail offer will be filed Monday and it will be a "very, very significant" cash amount.

Swiss authorities rejected an offer Friday, considering the 76-year-old filmmaker awaiting a decision on extradition to the United States a high flight risk. They noted it was not a cash offer.

Herve Temime told France-Info radio Sunday the latest offer is in cash. He wouldn’t say how much. He said Polanski would accept the extradition decision "whatever it is" and assured his client would never behave "like a fugitive."

Polanski, arrested Sept. 26, is wanted in the U.S. for having sex with a 13-year-old girl in Los Angeles in 1977. Polanski fled the U.S. before sentencing.
