Prosecutors in Poland have questioned filmmaker Roman Polanski at the request of U.S. prosecutors who are seeking his extradition on charges from 1977 of having sex with a minor.

A spokeswoman for the prosecutors in Krakow, Boguslawa Marcinkowska, said Thursday the filmmaker remained free but available for further proceedings. She said prosecutors must analyze the U.S. arrest and extradition request before they make any decisions.

Deputy Foreign Minister Rafal Trzaskowski said the charges against Polanski have expired in Poland, providing no grounds for an extradition.

The director is living in Paris, where — as French citizen — he is immune from U.S. justice, which he fled in 1978. In 2010, he was freed from Swiss house arrest after that government refused to extradite him.
