Meanwhile, both of Wiesenthal's employers terminated his services in 1960, as there were too few refugees left in the city to justify the expense. Wiesenthal opened a new documentation centre (the Documentation Centre of the Association of Jewish Victims of the Nazi Regime) in Vienna in 1961. He became a Mossad operative, for which he received the equivalent of several hundred dollars per month. He maintained files on hundreds of suspected Nazi war criminals and located many, about six of whom were arrested as a result of his activities. Successes included locating and bringing to trial Erich Rajakowitsch, responsible for the deportation of Jews from the Netherlands, and Franz Murer, the commandant of the Vilna Ghetto. In 1963 Wiesenthal read in the newspaper that Karl Silberbauer, the man who had arrested famed diarist Anne Frank, had been located; he was serving on the police force in Vienna. Wiesenthal's publicity campaign led to Silberbauer being temporarily suspended from the force, but he was never prosecuted for arresting the Frank family.
