After fleeing an Allied prisoner of war camp in Germany after the war, Rauff escaped to Chile, where he was recruited for the BND by Rudolf Oessger-Roeder, another ex-SS man. The BND's records show that Rauff was paid 70,000 marks (about $60,500).
One of Rauff's tasks was to infiltrate Castro's Cuba to supply German intelligence with information about the revolutionary leader.
However, the documents show that Rauff's pay was halved in 1962 because his mission had failed.
Despite the BND's readiness to recruit Nazi war criminals, Germany's justice authorities caught up with Rauff in the 1960s. By the end of 1962, Chile had arrested him and had initiated steps to extradite him to West Germany to stand trial.
However, as the crime of murder was subject to a 15-year statute of limitation in Chile at that time, he was freed after spending only a few months in custody. Rauff never answered for his crimes, dying in Chile in 1984 at the age of 77.
The revelations follow recent disclosures that the BND mysteriously "lost" a 500-page file on the 99-year-old Nazi war criminal Alois Brunner.
