MICHAEL Jackson's body was riddled with needle marks when he died, indicating possible use of a powerful sedative at the centre of the investigation into his death, US media has reported.

CNN and ABC News on Wednesday both cited unidentified sources involved in the probe as saying multiple track marks and several collapsed veins were discovered after Jackson's body was examined following his death on June 25.

The marks on Jackson's body "could certainly be consistent with the regular IV use of a drug, like Diprivan," CNN quoted the source as saying.

Several bottles of Diprivan, the brand name for the potent sedative propofol, were reportedly found at Jackson's home after his death.

Diprivan is commonly used to induce unconsciousness in hospital patients ahead of major surgery.

Experts say there is no conceivable reason why Jackson could have had the drug at his home and that it should only be administered by a trained anesthesiologist.

Last week, a nutritionist who worked with Jackson earlier this year told CNN in an interview the star had pleaded with her to acquire Diprivan.
