Fred Davis Clark, Jr. — a Cayman Islands man who was accused of securities fraud in a civil suit filed Jan. 30 by the Securities and Exchange Commission — sold his ownership interest and resigned his posts at a separate Cayman Islands business a day before the SEC suit was filed, according to a spokeswoman for the firm, CMZ Group Ltd.

CMZ Group Ltd., a Cayman Islands company that includes a Caribbean pawn shop network among other ventures, said in a statement that Clark “is no longer affiliated with our company, and, in fact, separated from the company before (Jan. 29) the U.S. SEC complaint was filed (Jan. 30th.)’’

The SEC had identified Clark, 54, as “co-chairman of CMZ’’ in a complaint that accused him and four other former real estate executives at the defunct Cay Clubs Resorts and Marinas of defrauding nearly 1,400 investors of more than $300 million in an alleged Ponzi scheme between 2004 and 2007.

“We put in our complaint the most current information available,’’ Eric Bustillo, director of the SEC’s Miami regional office, said Tuesday. The SEC complaint is pending in U.S. District Court in Miami. A hearing hasn’t been set.

According to the SEC suit, Clark operated Cay Clubs Resorts from his home in Key Largo and moved to the Cayman Islands after the real-estate investment business closed, leaving investors hanging.

Jeffrey L. Cox, a Boca Raton attorney for Clark, declined to comment Tuesday.
