On charges of “threatening a federal agent.”
A self-professed spokesman for the computer hacker group Anonymous was arrested by authorities in Dallas, officials said on Thursday.
“He was arrested and brought in for booking about 11 p.m. last night,” said Dallas County Sheriff’s spokeswoman Carmen Castro.
She didn’t know why Barrett Brown, 31, was arrested, saying there was no offence listed on the booking sheet. Brown was turned over to the FBI, she said.
A spokesman for the FBI declined to comment.
A Twitter account for the California law firm Leiderman Devine said it would be defending Brown at a hearing in Dallas federal court later on Thursday and that he had been detained on charges of “threatening a federal agent.”
Brown has been under the eye of law enforcement for some time and was interviewed by the FBI in March when authorities revealed that Hector Xavier Monsegur was the person behind Sabu, the colourful leader of Lulz Security, an offshoot of Anonymous.
Anonymous and other loosely affiliated hacking groups have taken credit for carrying out attacks against the CIA, Britain’s Serious Organized Crime Agency, Japan’s Sony Corp, Mexican government websites and the national police in Ireland. Other victims included Rupert Murdoch’s UK newspaper arm News International, Fox Broadcasting and Sony Pictures Entertainment.
Authorities have been attempting to beat back the intrusions and have arrested a number of the groups’ key players.
Brown has been faulted by many members of Anonymous for using his real name and for being quoted as a representative of the group, which prides itself on being loosely knit and having no clear leaders.
Brown did not immediately return a message left on his cell phone on Thursday.
Several websites posted what they said was video of Brown conducting a web chat as officers arrived, yelling “get your hands up!”
