TMZ is now reporting that Prince may have been treated for a drug overdose six days before his death.

Just hours after he performed in Atlanta on Friday (Apr. 15), Prince’s private jet made an emergency landing in Moline, Ill., only 48 minutes from his home. His reps claim he was battling the flu, but sources tell TMZ that he was hospitalized and doctors gave him a “save shot,” which is usually administered to counteract the effects of an opiate.

Doctors reportedly advised Prince to remain in the hospital for 24 hours. His people requested a private room, but decided to leave when their demands were not met. He was released three hours later and flew home. When he left, he was reportedly “not doing well.”

Authorities in Minnesota are trying to obtain hospital records to determine cause of death.
