According to Delray Beach police, the former Jackass star went missing on Monday, leaving in a black SUV to attend another facility.
Margera is alleged to have been at rehab under court order and staff there were “concerned he seemed to be leaving without authorisation”.
It comes as the star recently claimed he was fired from participating in the Jackass Forever film for refusing to go through “contract-mandated rehab”.
He also slammed the film’s director Jeff Tremaine and said fellow performer in the franchise Johnny Knoxville had “betrayed him”, claiming that the pair had made him “jump through hoops” before he eventually left the production.
Margera said: “My family – Jackass – has betrayed me, rejected me, abandoned me. Not all of them. I love all of them and they love me back. But specifically Jeff Tremaine and Johnny Knoxville.
“So I feel like my family has f**king done everything horrible to me and made me jump on hoops and walk through eggshells—which is impossible – and strung me along like a f**king puppet to get the $5 million I usually get when I make a movie with them because Jeff Tremaine and CKY has started it.”
Margera is seeking help for manic bipolar disorder and the American skateboarder and stunt performer recently posted on his Instagram posing with his new Alcoholics Anonymous sponsor.
