Late pop legend Michael Jackson's physician Conrad Murray didn't tell paramedics that he had given powerful painkiller propofol to the singer, says a report.

The Emergency Service Medical Report revealed that there were two attempts to restart Jackson's heart at his home and a third in the ambulance on the way to hospital, reports telegraph.co.uk.

It said when the paramedics arrived Murray was performing CPR and had attached an intravenous drip to Jackson's left leg, however the singer had no blood pressure or pulse and his pupils were dilated.

The paramedics twice used the drugs epinephrine and atropine to try to start Jackson's heart. They also put a tube in his throat to try to re-start breathing, and injected bicarbonate into his neck. The attempts failed and he was taken to hospital.

According to the report, Murray told paramedics that Jackson had taken the sedative lorazepam and fluids to rehydrate him after a sleepless night. However, he later told police that he had also given Jackson propofol to help him sleep, the media report said.

The Los Angeles coroner cited propofol as the cause of Jackson's death, with other drugs as contributing factors.

The report could be used used by prosecutors who have charged Murray with involuntary manslaughter over the singer's death June 25 last year.
