Bill Tanner, a double agent working for the FBI and the Naval Investigative Service, began a sting operation by walking into the East German Embassy in Washington DC and offering to sell classified information he obtained while working as a civilian engineer at the Naval Electronic Systems Engineering Center in South Carolina.  The operation ultimately lead to the 1983 arrest of Alfred Zehe.
