A court in London has recommended that a British man be extradited to the United States to stand trial on charges of hacking into US Government computer systems. American authorities have described Gary McKinnon, 40, as the "biggest military computer hacker of all time". Mr McKinnon is accused of gaining access to more than 90 computers in 2001 and 2002. They included computers at the Pentagon, NASA, Army bases and a naval station. His actions brought the entire military district of Washington to a standstill. He denies causing malicious damage and says he was looking for information on UFOs.His legal team says that if he was sent to America, he could end up in Guantanamo Bay - an allegation dismissed by the US Department of Justice. Mr McKinnon's case is expected to be passed to the Home Secretary for a final decision. Mr McKinnon says he will appeal to the High Court if the Home Secretary approves his extradition.
