WASHINGTON  Pfc. Bradley E. Manning, the Army intelligence analyst accused of leaking government files to WikiLeaks, will be stripped of his clothing every night as a “precautionary measure” to prevent him from injuring himself, an official at the Marine brig at Quantico, Va., said on Friday.

Private Manning will also be required to stand outside his cell naked during a morning inspection, after which his clothing will be returned to him, said a Marine spokesman, First Lt. Brian Villiard.

“Because of recent circumstances, the underwear was taken away from him as a precaution to ensure that he did not injure himself,” Lieutenant Villiard said. “The brig commander has a duty and responsibility to ensure the safety and well-being of the detainees and to make sure that they are able to stand trial.”
