The files also feature private investigators' reports, phone transcripts and many hours of audio tapes.
They files also describe how Jackson was once caught by a household staff member while groping a world-famous child star, viewing porn films while molesting another boy and fondling genitals of third in his private cinema.
Ironically, a lot of the damning reports in the collection of FBI were commissioned by the singer himself.
Other kids, the singer abused include a European boy and the sons of a screenwriter.
At least three kids received hush money, an investigator said, with family of one well-known young film actor receiving 392,000 pounds to avoid contact with all types of media, the Mirror reported.
The gagging order also that there would no attempt now or in the future to extort, intimidate, harass or impede Jackson.
A maid who worked for Jackson at Neverland was believed to have been paid off 1.3million pounds after complaining that her son was been abused by her employer.
