Medical Examiner's have released the cause behind Prince's death

US singer Prince died from an accidental overdose of the painkiller fentanyl, medical examiners have found.

The report, from the Midwest Medical Examiner's Office in Minnesota, comes more than a month after the singer was found slumped in a lift at his home.

According to the autopsy report, Prince self-administered fentanyl, an opioid many times more powerful than heroin.

Prescription painkillers were in the singer's possession following his death, officials told US media in May.

Prince was found unresponsive in a lift at his Paisley Park Studios on the morning of 21 April, local officials said. First responders tried to revive him with CPR but he was pronounced dead shortly afterwards.
