Tests have shown that superstar musician Prince died of an opioid overdose.
A law enforcement official, who is close to the investigation, told AP this was established by tests after the singer’s death in April.
The 57-year-old singer was found dead on April 21 at his Minneapolis-area estate. The official, who is close to the investigation, spoke on condition of anonymity because he was not authorised to speak to the media.
A single page report is said to have stated that Prince “self-administered fentanyl” – a synthetic opioid many times more potent than heroin.

The findings confirm suspicions that opioids played a role in the musician's death.
The Star Tribune in Minnesota also quotes a separate source with knowledge of Prince's death investigation who says he died from an overdose of painkillers.
Prince's death came less than a week after his plane made an emergency stop in Moline, Illinois, for medical treatment as he was returning from a concert. The official said Prince was found unconscious on the plane and that first responders gave him a shot of Narcan, an antidote used in suspected opioid overdoses.
It was reported shortly after Prince's death that the highly addictive painkiller Percocet - which contains both acetaminophen and oxycodone - had been found in his system.
Prince was pronounced dead at 10:07 a.m. on April 21.
