An undated handout picture released by the Greek Cypriot police on July 1, 2010 shows 54-year-old Christopher Metsos, a key suspect in the Russia-US spy scandal who was arrested at Larnaca airport in Cyprus on June 29, 2010 after immigration officers discovered his name on a stop list. The disappearance of Metsos provided a stunning twist to a Cold War-style espionage saga that has threatened to upset major efforts to reset ties between Washington and Moscow.
