MINNEAPOLIS (AP) — A Minnesota doctor saw Prince twice in the month before his death, including the day before he died, and prescribed him medication, a search warrant says.

Dr. Michael Todd Schulenberg treated Prince on April 7 and April 20, and he prescribed "medications and prescriptions" for the musician, according to the warrant, which was filed Thursday in Hennepin County and obtained by KSTP-TV and the Los Angeles Times.

Investigators interviewed Schulenberg and searched a suburban Minneapolis hospital where he worked. The warrant did not specify what medications were prescribed for Prince or whether he took them.

Lesa Bader, a spokeswoman for North Memorial Medical Center, said Schulenberg was a primary care physician at its Minnetonka clinic but he no longer works for the health care system.
