Following the 1975 West German Embassy siege in Stockholm , the German Red Army Faction ( RAF ) terrorist Norbert Kröcher allegedly planned to kidnap Anna-Greta Leijon . The goal was to exchange Leijon for 8 of his comrades held in German prisons . The plan , known as Operation Leo , was intercepted by the Swedish Security Service ( Säpo ) and Kröcher was arrested on 31 March in Stockholm . He was deported from Sweden in 1977 and jailed in Germany . He was released in 1989 and did not rejoin the RAF . Leijon was chosen as the kidnapping victim because she had the responsibility for the terrorist legislation and was ultimately responsible for the expulsion of the RAF terrorists who carried out the embassy siege
