The singer was hospitalized on Sunday

UPDATED: Tom Petty is off life support and “clinging to life,” according to TMZ, following a hospitalization for cardiac arrest on Sunday.

Citing the Los Angeles Police Department, CBS News previously reported Petty had died. But in a statement online, the LAPD walked back reports of the singer’s demise.

“The LAPD has no information about the passing of singer Tom Petty. Initial information was inadvertantly provided to some media sources,” the department wrote. “However, the LAPD has no investigative role in this matter. We apologize for any inconvenience in this reporting.”

The 66-year-old was reportedly found in his Malibu, California home on Sunday night. Petty was rushed to UCLA Santa Monica Hospital, where he was put on life support; TMZ states a decision was reportedly made to remove Petty from life support after it was found that he was lacking brain activity.

The Los Angeles County Fire Department did not confirm a name when reached by EW sister site PEOPLE, but did confirm they were dispatched to the home of an elderly unconscious male around 10:45 p.m. on Sunday night and transported him to a local hospital.

The rockstar wrapped his most recent tour — which he teased last year would likely be his “last big one” — last week at the Hollywood Bowl in Los Angeles. Along with his fabled backing band, the Heartbreakers, the group had launched the run in support of their debut LP’s 40th anniversary.

“I’m thinking it may be the last trip around the country,” Petty told Rolling Stone. “It’s very likely we’ll keep playing, but will we take on 50 shows in one tour? I don’t think so. I’d be lying if I didn’t say I was thinking this might be the last big one. We’re all on the backside of our sixties. 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.”
