NEW YORK ( TheStreet) -- Federal authorities arrested a trader on Thursday for allegedly threatening to kill 47 officials from the Securities and Exchange Commission and three other regulatory groups.

Federal Bureau of Investigation authorities arrested Vincent McCrudden, the 49-year-old head of Alnbri Management LLC, at Newark Airport. The Department of Justice is accusing McCrudden of threatening to kill people on an "execution list" posted to a Web site and advocating others to "go buy a gun" and join him.

McCrudden is scheduled to appear before Magistrate Judge E. Thomas Boyle in U.S. District Cour in Central Islip near his home in Dix Hills, Long Island, after 2 p.m. on Friday. He faces a maximum of five years each of two counts if convicted.

McCrudden allegedly posted the threats after having conflicts with officials from the SEC, the Commodities Future Trading Commission, the National Futures Association and the Financial Industry Regulatory Authority (Finra).

The CFTC has denied his requests to become a commodity pool operator, saying he had issued false account statements that overstated the value of a commodity pool he operated in the 1990s. In early December, the agency brought a civil enforcement action against McCrudden and two corporations linked to him for allegedly operating unregistered commodity pools. Finra also fined McCrudden and suspended him from trading last year for allegedly sending "threatening, abusive, intimidating, harassing, coercive, and vulgar communications" to his one-time employer, Hedge Fund Capital Partners.

According to the FBI complaint, McCrudden responded by sending a profanity-laced email to a CFTC attorney on Dec. 16 whose subject line was, in part, "You're not getting away with this. ... Merry Christmas!" In a email hours later with a similar tone, the FBI says McCrudden suggested that other CFTC attorneys were "either terrorist or Al Qaeda or something."

Meanwhile, on the Web site of his company, the FBI says McCrudden posted antagonistic messages that became increasingly hostile as time wore on. In an initial post, he allegedly urged visitors to "Stop paying your taxes. Go buy a gun, and lets get to work in taking back our country from these criminals. I will be the first one to lead by example."

McCrudden then allegedly posted an "Execution List" with the names of 47 current and former officials of the SEC, Finra, NFA and CFTC and offered visitors up to $100,000 for "the home numbers, addresses and any background information on the following corrupt government people." Included on the purported list were SEC Chairman Mary Schapiro and CFTC Chairman Gary Gensler, along with other employees of the agencies in New York and Washington.
