Los Angeles, June 21 (IANS): Late popstar Michael Jackson was found to have a sizable collection of pornographic material at his Neverland Ranch in 2003, according to police reports cataloging the property following a search of the residence.

Many of these books and videos are also detailed in court papers from the time, submitted after a boy came forward claiming that he had been sexually abused and assaulted by the singer on multiple occasions.

The police report claims that in Jackson's bedroom and bathroom alone there were at least seven collections of work found by investigators that show boys in their teenage years -- and in some cases younger -- fully nude or partially clothed, reports dailymail.co.uk.

One of the collections is described in court papers as: "Nude photos of teenage boys from late 1800s". 

Radaronline.com first obtained the police report and court papers, and an investigator on the case told them: "The documents exposed Jackson as a manipulative, drug-and-sex-crazed predator who used blood, gore, sexually explicit images of animal sacrifice and perverse adult sex acts to bend children to his will." 

"He also had disgusting and downright shocking images of child torture, adult and child nudity, female bondage and sadomasochism." 

The report states that many of the materials featuring naked men and women in the home could be used for the purpose of trying to attract young men. 

After the descriptions for many of the materials, the investigator noted: "Based on my training, this type of material can be used as part of the 'grooming' process, by which people (those seeking to molest children) lower the inhibitions of their intended victims and facilitate the molestation of said victims." 

These materials include "a book depicting nude children" found in the singer's "arcade room"; "a book which contained nude photographs of men" in the "master bathroom"; and multiple books found in the "master bedroom" that included one with "naked and semi-naked gay men" and another with "pre-teen or early teenage individuals" who in some cases were "nude or semi-nude". 

He was accused of sexually assaulting Gavin Arvizo, a 13-year-old cancer survivor at the time of the alleged incidents. 

Jackson was acquitted in 2005 on seven felony counts of child molestation and two felony counts of providing an intoxicant to a minor.
