A Dix Hills, N.Y., man accused last month of running unregistered commodity pools was arrested for allegedly threatening to kill officials of U.S. financial regulatory agencies, including the Securities and Exchange Commission and Commodity Futures Trading Commission.

Vincent P. McCrudden, 49, was picked up yesterday at Newark Liberty International Airport in New Jersey, according to Robert Nardoza, a spokesman for U.S. Attorney Loretta Lynch in Brooklyn, New York.

McCrudden and two companies he controlled were sued in December by the CFTC for operating commodity pools in violation of the Commodity Exchange Act. McCrudden threatened to kill “any and all of 47 current and former officials” of the SEC, the CFTC, the National Futures Association and the Financial Industry Regulatory Authority, according to the complaint.

“Go buy a gun, and let’s get to work in taking back our country from these criminals,” McCrudden wrote on one of his websites, according to the complaint. “I will be the first one to lead by example.”

McCrudden is scheduled to appear in federal court today in Central Islip, N.Y.

“He’s a good decent guy, although somewhat short-tempered, and when he loses his temper, he’s ill-mannered,” his lawyer, Bruce Barket of Garden City, N.Y., said in a phone interview.

“The timing for his latest literary efforts is particularly bad. Other than that, he’s a decent, hard-working guy who doesn’t pose a threat to anybody. It’s unfortunate but not a crime.”
