Turkish-Iranian businessman Reza Zarrab photographed at New York restaurant
Zarrab, who was dining with a woman in Nobu, left the restaurant after he noticed that he was recognized by people around him.
The woman was identified by Turkish media on Sept. 13 as Ayşegül Akgün, a former fan and estranged friend of Zarrab's ex-wife and singer Ebru Gündeş.
After his arrest in the U.S., Zarrab had initially pleaded not guilty then flipped, becoming a U.S. government witness.
Admitting being involved in the multibillion-dollar gold-for-oil scheme to subvert U.S. economic sanctions against Iran, Zarrab struck a deal with the prosecution for a more lenient sentence.
He became the U.S. prosecution’s top witness in the trial, leaving former Halkbank deputy general manager Mehmet Hakan Atilla as the only arrested defendant of the case.
