The family of the late US musician Prince is suing his doctor over claims he failed to treat him for an opioid addiction.
The family’s lawsuit alleges that failures by Dr Michael Schulenberg played a “substantial part” in the star’s death.
Prince died from an accidental overdose of fentanyl, a powerful opioid, in April 2016.
Dr Schulenberg has denied any wrongdoing, although he paid $30,000 to settle a federal civil violation alleging that he prescribed a drug illegally.
But the family’s lawsuit filed in Hennepin County District Court this week alleges that Schulenberg and others had “an opportunity and duty during the weeks before Prince’s death to diagnose and treat Prince’s opioid addiction and to prevent his death. They failed to do so.”
