New York hedge fund billionaire and philanthropist Michael Steinhardt has handed over $70 million worth of antiquities after a criminal probe found the items he had acquired were stolen.

Steinhardt, who is one of the world’s largest ancient art collectors, agreed to surrender the 180 items to avoid facing any criminal charges, Manhattan District Attorney Cy Vance said on Monday.

As part of the deal, Steinhardt is also subject to an unprecedented lifetime ban on acquiring any more antiquities.
