UPDATE 1-U.S. CFTC wins Hunter Wise precious metals fraud case

(Adds detail from release)

WASHINGTON, May 22 (Reuters) - The U.S. Commodity Futures Trading Commission notched up a legal victory on Thursday, as a court ordered a group of precious metals firms and their owners to pay $108 million in fines and restitution for fraud.

The Southern District Court in Florida said Hunter Wise Commodities and three related companies, as well as two of their managers, defrauded thousands of retail customers, and ordered them to pay back $52.6 million in restitution.

The companies, and Fred Jager and Harold Edward Martin, Jr., were also ordered to pay a civil monetary penalty of $55.4 million to the futures and swaps regulator.

Senators last month scolded the CFTC for not doing enough to prevent scam artists from luring retirees into risky investments in precious metals - often in Florida.

Jager, Martin and other employees claimed to arrange loans to buy gold, silver, platinum and other precious metals, the order said, and charged high interest and storage fees for metals that customers thought they had bought.

But in fact, no metal was ever bought, and more than 90 percent of retail customers lost money, the order said.

The CFTC settles the vast majority of the cases it litigates. In the past three years, only two cases went to trial, according to the agency. The CFTC won both.
