The Federal Bureau of Investigation (FBI) kept records on the American singer Michael Jackson, which were released under the Freedom of Information Act posthumously on December 22, 2009. In response to perceived threats against Jackson and allegations of child sexual assault made against him, the FBI made several investigations into Jackson, none of which led to charges.
Between 1993 and 2005, Jackson was investigated by California law enforcement agencies due to allegations of child abuse; the FBI provided technical and investigative assistance. They also investigated threats made against Jackson and others by Frank Paul Jones, who was later imprisoned. These investigations occurred between 1993 and 2005. The FBI found no evidence of criminal conduct on Jackson's part.
The FBI files comprise over 600 pages; 351 pages were released publicly, divided into eight parts. They include copies of letters from members of the public commenting on Jackson's performances, newspaper clippings, and various documents reporting that Jackson was the target of threats and extortion attempts. The files received extensive media coverage.
