TMZ reports Brown left a facility treating him for anger management, which he had entered 16 days ago following a reported altercation in Washington D.C.
Brown's lawyer, Mark Geragos, told TMZ his client must begin the community service he's required to perform, which stems from the Rihanna assault case.
The judge previously rejected the hours Brown claimed he had done, ordering him to repeat the process.
Geragos also said Chris will continue his anger management treatment in outpatient therapy.
Rapper Chris Brown has had to check out of a Malibu rehab facility so he can perform his court-ordered community service.
