The New York DA’s office fighting to stop trade of looted antiquities

Over the past six years, Matthew Bogdanos, a retired Marine colonel who has run the Manhattan DA's antiquities unit, has convicted a dozen people of antiquities trafficking

A Roman marble portrait head of the Greek philosopher Antisthenes was sold at the Chicago salesroom Hindman Auctions last week despite claims by a leading forensic archaeologist that the valuable artifact may have links to a disgraced antiquities dealer.

The sale, which made $100,000, had been opposed by Christos Tsirogiannis, head of the working group illicit antiquities trafficking, who said the head may have been linked to Robin Symes, a dealer who has been linked to looted antiquities.
