A Greek prosecutor on Tuesday charged a former curator of the American J. Paul Getty Museum with knowingly buying an ancient artifact which had been illegally dug up and smuggled out of Greece 13 years ago.

The accusation that former antiquities curator Marion True illegally obtained a 4th-century BC golden wreath is the latest controversy surrounding acquisitions she made for the wealthy Los Angeles-based museum.

True resigned from her post in a whirlwind of publicity last year when Italian authorities charged her with conspiring to receive stolen antiquities.

In the Greek investigation, police raided her Aegean island villa earlier this year and retrieved what authorities say are dozens of unregistered ancient objects.
