London, Dec 25 (ANI): An obsessed Janet Jackson fan had threatened to kill her brother Michael and thousands of his fans if he was not given half the pop king’s fortune, according to FBI files.

Frank Paul Jones had sent a number of disturbing letters.

In one he wrote: “Half of Michael’s estate is mine… if he doesn’t pay I’m going after him.”

He also said: “I’ll commit mass murder at a Michael Jackson concert if necessary, in an attempt to murder Michael, then you will have to deal with my situation in the public eye.”

But when there was no response Jones instead warned he would target President George Bush Senior, reports the Sun.

He wrote: “I decided that because nobody is taking me serious that I am going to Washington to threaten to kill the President of the United States.”

Jones was arrested outside the White House and later jailed.

Other FBI files revealed that how the ‘Thriller’ hitmaker was interrogated when he was accused of making obscene phone call to a British schoolboy.

The boy, who was 13 years old at the time, said the star told him he was fondling himself. (ANI)
