The Spanish secret service CNI mistook relatives of a top Pakistani politician for terrorists, prompting British police to detain them in London. CNI informed Scotland Yard that six members of a dangerous radical cell were flying from Barcelona to London to commit attacks. The warning followed the detention of several Pakistanis and Indians in Barcelona. The detainees relayed to Scotland Yard however, turned out to be relatives of Chaudry Sujaat Hussein – president of the Pakistan Muslim League, which support President Pervez Musharraf. They were flying to London to meet Musharraf, who was there at the time. When British police discovered their mistake, they put the detainees on a plane to Pakistan, and the British government apologized to the Pakistani authorities. The six have lodged a complaint at the British embassy in Pakistan and may take legal action against the CNI and Scotland Yard, according to Spanish reports.
