LONDON—British prosecutors say there’s not enough evidence to charge a British intelligence agent with any criminal offense arising from the interrogation of former Guantanamo Bay detainee Binyam Mohamed.
Police have been investigating an officer from the MI5 intelligence agency, identified only as Witness B, who questioned Mohamed in Pakistan in May 2002.
An officer of the MI6 agency is also under investigation.
Mohamed alleges that Britain was aware that the CIA sent him to be interrogated in Morocco, where he was tortured.
The government has announced a judge-led inquiry into allegations that British spies were complicit in mistreatment of detainees during the U.S.-led “war on terror,” but it cannot begin until the criminal investigations are completed.
