WARSAW, Poland -- An official says that Poland has been asked to extradite filmmaker Roman Polanski to the United States, where he is wanted on 1977 charges of sex with a minor.

Spokesman for the prosecutor general, Mateusz Martyniuk, told The Associated Press on Wednesday that the request from Los Angles prosecutors was being forwarded to Krakow, where Polanski's case is handled.

In October, Krakow prosecutors refused a U.S. request to arrest Polanski, 81, but questioned him and obliged him to turn up on every summons. He is to film in Poland in the spring.

Martyniuk said that as a rule Poland does not extradite its citizens.

Paris-born Polanski spent his childhood and youth in Poland but lives in France. He holds Polish and French passports.

In 2010 Switzerland refused to extradite Polanski.
