MINNEAPOLIS - A Minnesota doctor saw Prince twice in the month before his death, including the day before he died, according to a search warrant obtained by KARE 11.
The document also reveals Dr. Michael Schulenberg prescribed the late music icon medication. It states he treated Prince on April 7 and April 20. The prescriptions were filled at a Walgreens.
Investigators interviewed Schulenberg and searched a suburban hospital where he worked.
A spokeswoman for North Memorial Medical Center says Schulenberg was a primary care physician at its Minnetonka clinic but he no longer works for the health care system. A message left Tuesday at the physician's home wasn't immediately returned.
The search warrant, filed last week in Hennepin County, was supposed to be sealed however, according to a court spokesperson, it got separated from the seal order. "It should have never been released. It was human error," the spokesperson told KARE 11.
On Tuesday evening, authorities were seen at Prince's Paisley Park complex in Chanhassen. The Carver County Sheriff's Office said detectives were "revisiting the scene as a component of a complete investigation."
Officials at the scene would not respond to questions about what they were doing there. A man wearing a sheriff's department badge got out of an unmarked vehicles and yelled, "Open the gates!" to the private security company inside. The vehicles then moved through the gates and went around to the door of Paisley Park. A siren briefly sounded, and then the cars disappeared from view.
Prince died April 21 at his Minnesota home. Autopsy results are pending.
