obtained what appeared to be the case documents.
Among the books found, reports the Post, was one called Dress Up: Playacts and Fantasies of Childhood.
Jacko also kept a large collection of art books.
One was called Room to Play and features collage images of children.
Another was called Beach Portraits which was a collection of photographs of children on beaches in their swimming suits or underwear.
Jackson, who died from a drug overdose in 2009, strongly denied all allegations of sex abuse made against him and was cleared in the 2005 trial that followed the raid on his mansion.
It comes as two of his former boy companions, Wade Robson and James Safechuck , have taken part in the explosive new documentary film Leaving Neverland.
The pair both claim they were sexually abused by the singer over a number of years when they were children — claims that are rebuffed by Jackson's estate who claim the film is biased and one-sided.
STASH OF PORN Investigators also discovered adult porn magazines in Jackson’s bedroom and bathroom including Hustler’s Barely Legal and an issue of Girls Of Penthouse.
Cops also found drugs which could be used to treat sex addiction along with prescriptions written by several doctors, Radar reports.
In a video clip of the raid, officers can be seen moving a jukebox to reveal a seemingly hidden door in Jackson's games room.
One of the lead investigators can also be heard asking one of the Neverland staff about "secret rooms" at the property.
ESTATE'S DENIAL Michael Jackson’s estate slammed the release of the documents and pictures insisting the singer was an “amazing artist and humanitarian devoted to helping children in need”.
A statement read: “Michael Jackson's fans, including the Executors of his estate, prefer to remember the wonderful gifts Michael left behind instead of having to once again see his good name dragged through the mud by tabloid trash.
“Everything in these reports, including what the County of Santa Barbara calls ‘content that appears to be obtained off the Internet or through unknown sources’ is false."
