New York, Feb. 6 (Reuters): Australian actor Heath Ledger’s death was an accident caused by the abuse of prescription drugs, six of which were found in his body, the New York city medical examiner’s office said today.

Ledger, 28, renowned for his role as a gay cowboy in the 2005 movie Brokeback Mountain, was found dead in bed at his Manhattan apartment on January 22, naked and with prescription sleeping pills, painkillers and anti-anxiety medicine nearby.
