A billionaire financier and philanthropist has surrendered 180 allegedly stolen antiquities worth $70 million to the Manhattan District Attorney’s Office under an agreement that ends an extensive grand-jury investigation launched in 2017.

Michael Steinhardt, who made his billions through running a hedge fund and who prosecutors said is one of the world’s largest art collectors, also has agreed to a lifetime ban on acquiring any further antiquities, according to an announcement made by the Office of Manhattan District Attorney Cyrus Vance on Monday.
