Avrohom Y. Polack, widely known as Abraham or Abe Pollack, is a Brooklyn-based business figure and attorney who has represented various members of the Brooklyn Orthodox community. He was ensnared in the FBI's high-profile corruption and money laundering probe known as Operation Bid Rig. Operating out of a shared commercial space at 129-133 South 8th Street in the Williamsburg neighborhood of Brooklyn, Polack worked alongside Naftoly Weber to run an unlicensed money transmitting business, frequently referred to in federal documents as a 'cash house.' This operation served as a critical node in an underground financial network that converted bank checks into large quantities of physical currency, effectively bypassing state and federal banking regulations. Between January and July 2009, Polack and Weber facilitated the movement of illicit capital for various co-conspirators, most notably Rabbi Mordchai Fish of Congregation Sheves Achim. Polack was specifically identified by federal prosecutors as the source of $125,000 in physical cash provided to a cooperating witness (Solomon Dwek) and Fish. On November 16, 2010, Polack admitted to his role in the enterprise, pleading guilty in Newark federal court to a charge of conspiracy to operate an unlicensed money transmitting business. His conviction resulted in a sentence of probation, reflecting his cooperation or a lesser role compared to the primary architects of the Bid Rig scheme, alongside a significant financial forfeiture of over $179,000 in seized assets.
