Margera, 42, was reportedly placed into the Delray Beach treatment center as part of a court order and fled the facility after telling its manager that he was unhappy with its services, according to a Delray Beach Police report.
The report states that Margera told the manager that he instead planned to check himself into a different rehab center in the area before leaving in a black sedan.
Facility staff members said Margera didn't appear to be a danger to himself or others during the time of his departure. Local authorities searched for the 42-year-old on Monday and have not yet been able to locate him.
A source close to the former Viva La Bam star said he was staying at a sober living facility and had recently been involved in an argument with his wife, Nicole, and that Margera had issues with the facility's restrictions, which led to his decision to leave suddenly.
Margera had recently experienced a wrist injury following a bad fall while skateboarding and blamed the facility for not setting up his physical therapy appointments, TMZ reports.
The former reality show star had recently completed a year of treatment in relation to substance problems and was reported to be doing well, as close friends and family intend to find him and return him to the facility, TMZ reports.
Margera was one of MTV's most prominent television personalities in the early 2000s, starring on the reality stunt show Jackass and its spin-off series Viva La Bam, which focused on himself, his family and close friends.
