Minnesota police have released more logs of 911 calls about Prince — including a 2011 tip from a woman who said she was concerned about his "cocaine habits."
"He advised her last year in Germany that he cannot control his habit and she was advised to report it," the log reads.
The name of the caller was redacted, and the Carver County Sheriff's Office noted since the information was a year old and there was no indication the singer was "in immediate danger," the incident was marked as closed.
It was not clear why the woman waited so long to make the call, and there was no proof provided of any drug use. Prince did travel to Germany in 2010 for a European tour.
The 57-year-old superstar was found dead in an elevator at his Paisley Park spread on April 21. An autopsy was conducted but no cause of death has been released.
Federal law enforcement officials have told NBC News that prescription painkillers were found on Prince and and in his home, though it's unknown if they played a role in his death.
Prince's longtime attorney, Londell McMillan, has dismissed speculation his death could be linked to narcotics.
"Everybody who knows Prince knows he wasn't walking around drugged up," McMillan told the Associated Press last week. "That's foolish. No one ever saw Prince and said, 'He looks high.' It wasn't what he was about."
