The heavily redacted data packet reveals claims Hitler arrived in Argentina two and a half weeks after the fall of Berlin.

The information is said to have come from a source met by an FBI agent in Hollywood who was seeking “immunity from being sent back to the Argentina”.

Hitler’s survival was probed by the CIA in the 50s after a man claiming to be former Nazi officers came forward with a photo of Adolf.
