U.S. authorities have made another attempt to extradite director Roman Polanski back to the States to face punishment for his 1970s sex conviction.

The Rosemary's Baby moviemaker fled the country for Europe after pleading guilty to unlawful sex with a minor in 1978, and authorities have unsuccessfully tried to extradite him to the U.S. on a number of occasions in recent years.

On Wednesday (07Jan15), a spokesman for Poland's prosecutor general Mateusz Martyniuk told Associated Press they had received a new extradition request from America for the director and the matter will be sent to officials in the city of Krakow.

The 81 year old was detained for questioning in the city in October (14) but Polish officials let him walk free hours later. He is said to be preparing a film in the region.

Polanski's recent attempt to have the conviction formally dismissed was denied by a judge in December (14).
