Never-before-seen FBI files exclusively obtained by RadarOnline.com and co-plaintiff Emma Best (@natsecgeek) show Hubbard serving up fingerprints of his brainwashed followers directly to J. Edgar Hoover.
"I wish to thank you for the information," Hoover himself wrote to Hubbard on March 9, 1951.
Incredibly, it appears Hubbard sent the DNA stamps totally unsolicited, because Hoover politely informed him he didn't want them.
"I wish to advise you," the top G-man wrote, "that the FBI has no authority to handle fingerprints with the exception of those received from bona fide law enforcement departments and federal and state agencies."
RadarOnline.com's dossier of FBI files reveals Hubbard ratted out his followers in response to 1950s anti-communist hysteria.
As a March 7, 1951, FBI field office report stated: "Hubbard advised that he felt that communists within his organization were undermining its structure. He advised that he had turned over the names of several suspected communists to the FBI field office in Los Angeles."
Although he contacted the FBI three years before opening his first Church of Scientology, by 1951 Hubbard already had a rabid following for his crackpot Dianetics movement.
Current high-profile church members include Tom Cruise and John Travolta.
A longtime Scientology observer noted: "This is the worst possible news for the church. They think of Hubbard as some kind of god-like figure. That he was ratting out his own people in the most petty way will be almost impossible for them to swallow."
In October 2009, the FBI reported whispers of Scientology's "underground labor camps that resemble concentration camps."
Making matters worse are recent FBI investigations of the cult.
A Scientology spokeswoman said in 2013 the group was unaware of any probe, and the FBI, U.S. Attorney's Office and Justice Department have refused to confirm or deny the investigation took place.
