Opioid painkillers were found in the late pop star Prince’s home after his sudden death last year, unsealed court documents have revealed.

The papers, which were under seal until Monday, also stated that investigators were told that the musician had a history of withdrawals believed to be the result of prescription drug abuse.

According to a search warrant of his Paisley Park complex in Minnesota, “numerous narcotic controlled substance pills” were found in various containers – some of which had been prescribed to his body guard, Kirk Johnson, allegedly for the musician’s privacy.

Alongside these, quantities of other prescription pills were found in the artist’s home.

The Purple Rain singer died last year at the age of 57 after what was deemed to be an accidental overdose of the painkiller fentanyl, however no prescription made out to Prince for the drug has been found.
