Because of a series of high profile espionage arrests, the press dubbed 1985 "the Year of the Spy."That spring, the John Walker Spy Ring—John Walker, Jerry Whitworth, Arthur Walker, and Michael Walker—was arrested for passing classified material to the Soviet Union. On November 21, Navy intelligence analyst Jonathan Jay Pollard was arrested for spying for Israel. On November 23, Larry Wu-Tai Chin, a former CIA analyst, was arrested on charges of spying for the People's Republic of China since 1952. On November 25, former National Security Agency employee Ronald William Pelton, was arrested for selling military secrets to the Soviets. CIA employee Sharon Marie Scranage and boyfriend Michael Soussoudis were arrested in July for passing material to Ghanian intelligence.
