Greece's culture minister said Wednesday that he will meet with J. Paul Getty Museum director Michael Brand in Athens to press Greece's claim for the return of four ancient artifacts from the Los Angeles museum.

Greece claims the artifacts are among thousands believed to have been illegally exported as part of a booming trade in the country's priceless archaeological heritage.

Culture Minister Giorgos Voulgarakis said he was "extremely interested in the matter of the return of the Greek antiquities."

The Getty confirmed the May 16 meeting, and said in a statement, "We believe these discussions should take place between Dr. Brand and Greek officials and we will have no further comment at this time."

Also Wednesday, a second raid was launched on a villa owned by former Getty antiquities curator Marion True, police said.

True is standing trial in Italy for allegedly trafficking stolen antiquities. True has denied any wrongdoing.

Two marble coffins, eight marble roof tiles that would likely have come from an ancient temple and a stone mortar were among items found Wednesday during the raid on the Aegean island of Paros, police said. An earlier raid on the same villa at the end of March found several artifacts.

An April 12 raid of a shipping magnate's villa on the nearby Aegean Sea islet of Schoinoussa yielded about 280 unregistered ancient artifacts.

Greek authorities are investigating whether the artifacts are linked to the dispute between Greece and the Getty. Voulgarakis has said there is no evidence yet to back media reports of a link, and the Getty has said it has no connection with the seizures.
