Earlier, Petty was found unresponsive at his Malibu home. Paramedics reportedly found a pulse and Petty was taken to UCLA Santa Monica Hospital.

Last week, the singer concluded his tour - which began in April earlier this year - at the Hollywood Bowl, and he previously admitted the run on the road would likely be his "last big one".
He told Rolling Stone: "We're all on the backside of our 60s... I have a granddaughter now I'd like to see as much as I can. I don't want to spend my life on the road. This tour will take me away for four months. With a little kid, that's a lot of time."
