The noose tightened around prominent Anonymous-related leaders yet again, with the arrest late Wednesday of Barrett Brown of Dallas County, Texas. This marks the second time Brown has been raided by federal authorities.

Brown previously described himself as an Anonymous spokesperson, but announced his departure from the group last year. He is now being held in federal detention in Dallas on charges of threatening a federal agent, according to his attorney’s Twitter account.

That same law firm, Liedermann Devine of Ventura, California, tweeted on Thursday afternoon that he also "needs a local Dallas atty ASAP."

The arrest came just hours after Brown posted a 13-minute YouTube video entitled "Why I'm Going to Destroy FBI Agent Robert Smith.”

In the video, Brown smokes, laughs, and appears to be getting increasingly irate. He accuses FBI Agent Robert Smith of harassment, saying that Brown’s mother has become a target of surveillance by the FBI, and was facing obstruction of justice charges.

"Robert Smith's life is over," Brown said on the video.

Previously, Brown had threatened to hack the Zetas, a powerful Mexican drug cartel.

"I have reason to fear for my life, not just from the Zetas, but from the US government," he said in the video. Brown went on to note he would treat any intruders into his home, including federal agents like the FBI, as potential Zeta attackers.

Just last year, Brown spoke with Ars and said "the rule of law is void." Since his departure, many members of Anonymous have distanced themselves from Brown. These members say he’s been too self-aggrandizng and does not represent the group as a whole.
