Michael Jackson RX

We've learned Beverly Hills Police have just responded to the office of Dr. Arnie Klein, Michael Jackson's close friend and doctor.

We're told Klein's office asked the cops to come -- someone in the office told us they called for protection. We do not have further details.

UPDATE: Cops tells us Dr. Klein's office has been receiving "suspicious calls" today -- so they took a report and are going to investigate.

A doctor who treated Michael Jackson claimed the singer self-injected Demerol into his system.

We've combed through tens of thousands of pages of the official file for the 2005 molestation trial. In the Santa Barbara County Sheriff's notes, a member of Jackson's security detail -- retired L.A. County Sheriff's deputy Michael Laperruque -- said some doctors were trying to get Jackson off of Demerol, and that one of the doctor's in Santa Barbara "was upset with JACKSON because he had been self-injecting."

Laperruque told detectives he had picked up Jackson's prescriptions for the singer, usually under the name Chris Carter. Carter was one of Jackson's bodyguards.

Laperruque also told detectives one time when he was at Neverland his job was to keep Jackson's family out because they were planning an intervention.

Michael Jackson had injection sites on his neck, according to law enforcement sources.

As we first reported, Jackson had "dozens" of injection sites and punctures all over his body the day he died. Law enforcement sources tell us some of these injection sites and punctures were old and some were fresh. They were found, we're told, on his upper arms, upper legs, ankles, inside around his knees and the neck.

Dr. Arnold Klein told Larry King, "

." Klein, who saw Jackson multiple times in the weeks before his death, did not explain why he didn't notice marks on the singer's neck and other places.

We've obtained documents that were part of the Sheriff's Department's investigation detailing what was found in the search. Among the items ...

-- A vial of Versed -- a powerful sedative
-- Several IV bags containing "a milky white fluid, located in a small cardboard box on top of the bathtub." Propofol and other anesthesias are milky white. As we first reported, Propofol was in Jackson's home the day he died.
-- A vial of Promethazine -- an antihistamine with strong sedative effects
-- A bottle of Alprazolam (generic for Xanax, a powerful anti-anxiety drug)
-- A bottle of Percocet -- a painkiller
-- A syringe
-- A vial with Demerol in it
-- Numerous loose pills outside bottles
-- A bottle of Prednisone -- a steroid
-- Ery-tab -- an antibiotic
-- Prescriptions for Xanax that had been filled
-- A prescription for Alprazolam
-- Oxygen tanks
-- IV stands

In the documents obtained by TMZ, a former bodyguard of Michael Jackson's says he was a bagman for Jackson and the mission was Xanax.

Chris Carter told Santa Barbara County Sheriff's Deputies he would pick up prescriptions for Xanax for Jackson at various pharmacies, and that Jackson was taking 10 plus Xanax pills a night.

Carter told detectives he expressed concerns to another Jackson employee, who said the singer was actually doing better -- because he had been taking 30 - 40 Xanax pills a night.

Sheriff's detectives interviewed Chris Carter, who worked as Jackson's bodyguard prior to the Sheriff's raid of Jackson's home in 2003. According to Sheriff's Department notes obtained by TMZ, Carter said he would get Xanax prescriptions for Jackson under various fictitious names. Carter told detectives that Jackson would even use his name and the names of other employees to score prescriptions.

In addition to using his name, Carter said Jackson would use the names of Frank Tyson (a Jackson employee who was a prominent figure in the molestation trial, having had numerous contacts with the accuser's family), Jesus Salas (Ranch manager) and Joe Marcus (another Jackson employee) to get prescriptions.

Various pill bottles were found at Jackson's Neverland Ranch. One bottle of Alprazolam (generic for Xanax) was prescribed for Frank Tyson by Dr. Arnold Klein. A bottle of Prednisone found at the Ranch was also prescribed by Dr. Klein in the name of Peter Midani.

A bottle of Percocet, a narcotic painkiller, was found with the name Michael Armstrong, prescribed by Dr. Gerald Labiner.

A bottle of ERY-TAB, an antibiotic, was found with the name "M,M." The prescribing doctor was Dr. Carey Logan from Las Vegas.

A prescription receipt from a pharmacy was found for Alprazolam (generic Xanax) and written for Frank Tyson by Dr. William VanValin. Another receipt from Dr. VanValin was for written for Xanax in the name of Manuel Rivera.

Michael Jackson used to leave the offices of various doctors looking "out of it," according to a former bodyguard who was interviewed by detectives during the 2004 child molestation investigation.

Chris Carter, a former Jackson bodyguard, was interviewed by detectives from the Santa Barbara County Sheriff's Department. Carter told detectives he would drive Jackson to doctors' offices in New York, Florida and California. The Sheriff's documents, obtained by TMZ, say "[Carter] named Dr. [Arnold] Klein, Dr. [Allan] Metzger, Dr. Barney from Solvang, Dr. Saunders and Dr. Farshchian."

The notes continue, "Carter described JACKSON as being sharp and 'in tune' prior to the doctor visits and afterward he would be out of it and sedated."

The notes also say "Dr. Farshchian told him that JACKSON was addicted to Demerol, but said he was giving JACKSON a placebo to wean him off."

Carter talks of an incident where Jackson was intoxicated in a hotel room and fell on his face. Carter said he confronted Jackson and spoke with him about his drug problem for an hour. Carter said Jackson denied having a problem. According to the notes, "Carter said he told Jackson he was not comfortable in getting prescriptions for him." Carter says he then quit being Jackson's bodyguard as a result.

As far as drug use is concerned, Joe says he didn't know anything about it but said whatever Michael took he did so he could "relax and sleep."
