Jackson suffered a cardiac arrest on 25 June (09). Rumours have swirled about the circumstances leading up to his sudden passing, with reports suggesting he had a prolonged addiction to prescription painkillers.
Los Angeles police investigating the Thriller superstar's passing have recruited the help of the Drug Enforcement Agency (DEA) after discovering a number of pill bottles in his rented Holmby Hills, Hollywood mansion.
Several doctors who were known to have treated Jackson as a patient have also been questioned by cops over allegations they abused their power to write fake prescriptions for the late star - but Dr. Arnold Klein insists he was not one of the "criminals" who enabled Jackson's alleged habit.
Klein says, "I was not one of the doctors who participated in giving him overdoses of drugs or too much of anything.
"In fact, I was the one who limited everything, who stopped everything."
The medic claims he warned Jackson about the dangers of strong drugs like Dilaudid and Propofol, branding them "poison".
And Klein reveals he saw Jackson just three days before his tragic death - when the singer was in good health and high spirits as he showed off his fancy footwork in the dermatologist's office: "He danced in my office. He danced for my patients."
