LOS ANGELES(AFP) - Pop icon Prince was treated for a drug overdose in the week before his death on Thursday, entertainment website TMZ reported, citing multiple unnamed sources.

The 57-year-old was treated at a hospital after his private jet made an unscheduled landing in Moline, Illinois last Friday following a gig in Atlanta, amid reports that he had been battling influenza.

"Multiple sources in Moline tell us Prince was rushed to a hospital and doctors gave him a 'save shot'...typically administered to counteract the effects of an opiate," TMZ reported.

It quoted unnamed sources as saying Prince had been advised by medics to remain in the hospital for 24 hours but decided to leave after three hours when he couldn't get a private room.

"We know authorities in Minnesota are trying to get the hospital records from Moline to help determine (the) cause of death," said TMZ.

Prince, whose pioneering brand of danceable funk made him one of the most influential figures in music, was declared dead Thursday after being found unconscious in an elevator at his secluded compound in Minnesota.

News of his death prompted a flood of tributes, from US President Barack Obama to the Rolling Stones' Mick Jagger, as well as ordinary fans.

Prince's representatives did not immediately respond to requests for comment.
