The official ambulance report concerning Michael Jackson's death allegedly confirms rumours Dr. Conrad Murray misled medics at the scene.

Murray pleaded not guilty to a count of involuntary manslaughter in Los Angeles last month. He stands accused of administering the powerful anaesthetic Propofol which killed the King of Pop in June 2009, and is due to back in court on April 6, 2010, when a date for a pre-trial hearing will be set.

Editors at Britain's News of the World newspaper have obtained documents from the paramedics who treated Jackson on the day of his death - and the information could prove vital for the prosecution team.

The papers appear to show Murray failed to inform medics he had given the singer a dose of Propofol prior to his death, telling them he had only administered the sedative Lorazepam and fluids to rehydrate Jackson.

A source close to the Jackson family says, "This is the clearest suggestion yet that Murray misled the paramedics. Why didn't he tell them about the Propofol? We are sick at what this report indicates."
