Michael Jackson's doctor Conrad Murray told police the singer threatened to cancel his London O2 Arena gigs unless he was given drugs to help him sleep on the day he died, a Los Angeles court has heard.

When Detective Martinez interviewed Dr. Murray the physician also admitted he had been giving Jackson Propofol six nights a week for two months, but that he had been trying to wean him off the drug as he feared he was becoming addicted to it. The singer is said to have referred to the drug as his "milk".
