Prosecutors are using the arrest of a management consultant accused of violating the Iran Trade Embargo to show they are aggressively trying to stop money from flowing to Iran.

U.S. Attorney Preet Bharara said Mahmoud Reza Banki ignored the dangers of breaking laws designed to protect the United States when he set up a system so Iranians could move money internationally.

Banki was arrested Thursday. He’s accused of operating an unlicensed money transfer business. It was not immediately known who will represent the 33-year-old Manhattan resident in court.

Prosecutors said Banki operated the money transfer business for the last four years.
