Polina Breyter, 69, a former caseworker and employee of the Claims Conference who participated in a $57 million fraud scheme targeting programs established to aid the survivors of Nazi persecution, was sentenced Friday in Manhattan federal court to 18 months in prison.

According to Manhattan U.S. Attorney Preet Bharara, “Eighteen of 31 people charged have now pled guilty and face the same prospect of prison as a result of this wide-ranging fraud.”

In addition to her prison term, Breyter, of Brooklyn, New York, was sentenced to one year of supervised release, and ordered to forfeit $22,000 and pay restitution in the amount of $461,875.65.
