IOWA CITY, Iowa (AP) — Investigators are moving quickly to seize the wide-ranging personal assets of the founder of an Iowa brokerage who is accused of a $200 million fraud.

Former Peregrine Financial Group CEO Russ Wasendorf Sr. had been expected to appear in federal court for a detention hearing Wednesday, but it was delayed until next week. He's being held in an undisclosed location.

Workers who lost their jobs when Wasendorf's network of companies collapsed plan to meet with state officials Wednesday to apply for unemployment benefits and fill out paperwork seeking missing wages.

Officials appointed to manage Wasendorf's assets have made progress identifying real estate properties and several other companies he controlled. A lawyer for the receiver says he's hoping to make "substantial recoveries" for 24,000 customers who are missing money.
