The Federal Bureau of Investigations released on Tuesday some 200 pages of files relating to the child molestation cases against Michael Jackson and threats by a would-be assassin to kill the King of Pop in 1992, dpa reported.
The suspect in that case also threatened to kill then-US President George H W Bush, and eventually pleaded guilty to a charge of mailing a threatening communication and was sentenced to two years in jail.
The documents, released under the Freedom of Information Act, revealed that Los Angeles police called in the FBI to help to investigate the 1993 child molestation allegations against Jackson.
No charges were pressed against Jackson after the purported victim declined to cooperate following a reported 20-million-dollar settlement with the pop star.
The documents showed that the FBI also assisted Santa Barbara police to investigate Jackson in 2004 when he was indicted on charges that he molested a 15-year-old boy. The FBI also calmed local authorities who reported concerns that the court case could become an attractive terrorist target, the documents indicated.
