Washington ? Newly released documents show the FBI interviewed a naked, chained terror suspect back in 2002 as the bureau struggled with the CIA over how to treat high-value prisoners.

Details of the interrogation were contained in documents released late Friday as part of Freedom of Information Act lawsuits brought by the American Civil Liberties Union, Amnesty International, and Judicial Watch.

As the CIA began to use harsh interrogation techniques against captured terror suspects, the FBI became wary of the legality of the methods, which ranged from forced nudity to waterboarding, a form of simulated drowning. As a result, FBI agents were ordered not to participate in such harsh interrogations.

Yet sometime in late 2002, an FBI agent interviewed accused Sept. 11 plotter Ramzi Binalshibh at a CIA site. The agent later said he got valuable information out of Binalshibh before the CIA shut down the questioning.
