Federal officials have arrested an Army intelligence analyst who boasted of giving classified U.S. combat video and hundreds of thousands of classified State Department records to whistleblower site Wikileaks, Wired.com has learned.

SPC Bradley Manning, 22, of Potomac, Maryland, was stationed at Forward Operating Base Hammer, 40 miles east of Baghdad, where he was arrested nearly two weeks ago by the Army’s Criminal Investigation Division. A family member says he’s being held in custody in Kuwait, and has not been formally charged.

Manning was turned in late last month by a former computer hacker with whom he spoke online. In the course of their chats, Manning took credit for leaking a headline-making video of a helicopter attack that Wikileaks posted online in April. The video showed a deadly 2007 U.S. helicopter air strike in Baghdad that claimed the lives of several innocent civilians.
