New York, October 23 : A private detective who worked for O. J. Simpson has alleged that the former American football star once hired high-profile Los Angeles private investigator Anthony Pellicano to bug and harass his late ex-wife Nicole Brown.

"I know for a fact that Nicole Brown Simpson was a victim of stalking and that her cars and residence had been wiretapped," the New York Daily News quoted Bill Pavelic, the lead investigator for Simpson's defense team during his criminal trial for the murders of Nicole and Ron Goldman, as saying.

The 19-year veteran of the Los Angeles Police Department believes that Simpson hired Pellicano to employ the same bugging devices to tap Nicole Brown’s conversation as the investigator had planted at Michael Jackson 's Neverland Ranch.

"I saw it with my own eyes. The equipment in Nicole's house and car was almost identical to what he installed at Michael Jackson's," says Pavelic.

Although Pellicano was working for Jackson at the time, Pavelic says: "Pellicano was always working for two, or three, different sides — gathering information he can trade someday."

He believes that Pellicano's surveillance enabled O. J. to know when Nicole was seeing other men.

"Pellicano facilitated O.J.'s ability to stalk her," alleges Pavelic, who also believes Pellicano and other people working for him made numerous harassing calls to Nicole.

Pellicano is currently in prison for illegal wiretapping.

"Cops knew about Pellicano's wiretapping of Nicole," alleges Pavelic, who will tell more in his book, ‘Guilty of Incompetence’.

"Had Nicole not been murdered, his wiretapping would have been exposed long ago," he says (ANI)
