The FBI concluded the fan had broken no laws and the case was closed.

The Dutch fan investigated by the FBI also insisted he never intended to threatened Houston. The cassette recordings he sent were songs he'd written for the singer.

He told the agent he was the "President of Europe" and had purchased Brazil for $66 billion. He also claimed credit for the fall of the former South African government and for the election of Nelson Mandela in South Africa.

The man, who worked at a plant nursery in the Netherlands, promised not to send any more, the agent wrote.

Another FBI investigation centered on Houston's allegation that someone she knew was extorting her by threatening to "reveal certain details of her private life" to tabloids unless she paid $250,000 in November 1992. The unidentified person claimed to have "knowledge of intimate details regarding Whitney Houston's romantic relationships," an FBI report said.

Houston, in a December 1992 interview by the FBI, said she didn't know what the person might know, but the singer did talk about personal matters with the person, the heavily-redacted report said.

A letter sent to Houston's father by a lawyer for the person warned that they had "already turned down several offers... which are in the six figures range" for the story.

"Therefore, we would expect a similar offer from you with respect to the sale of... exclusive rights."

Her client "has suffered emotional stress" from her dealing with Houston and may sue, the lawyer said. "The fall-out will undoubtedly be negative," the lawyer warned Houston's father. Instead of meeting a November 23, 1992, deadline to pay, Houston's father called the FBI.

The FBI and U.S. attorney decided no laws were broken and the case was closed.
