The U.S. attorney in Chicago has formed a new team of lawyers to target securities and commodities fraud, Crain’s Chicago Business reports.

Zachary Fardon, U.S. attorney for the Northern District of Illinois, created the fraud section last month out of an existing financial crimes section of the office’s criminal division, which is made up of 40 attorneys handling mortgage issues and health care fraud, among other matters. The new team is made up of 12 prosecutors and is headed up by the former deputy chief of the financial crimes section, Assistant U.S. Attorney Jason Yonan. Prior to working for the U.S. attorney, Yonan was a Securities and Exchange Commission lawyer, Crain’s Chicago Business reports.
