Polanski, 76, and who holds French and Polish citizenship, was arrested in relation to a 30-year-old U.S. case involving sex with an underage girl, when he arrived in Switzerland in September to collect a lifetime achievement award at a Swiss film festival.
"All I know is that he has been taken from prison for medical attention. I don't know where he is or when he will be returned to prison," French lawyer Herve Temime told Reuters.
The Oscar Award-winning director pleaded guilty to having sex with a 13-year-old girl in 1977 and spent 42 days in prison. But, Polanski fled the United States before the case was concluded because he believed a judge would pass a tough sentence.
U.S. authorities have up to 60 days to make a firm extradition request. U.S. judicial sources have said the complex extradition process could take years if Polanski challenges it.
