TMZ announced singer Chris Brown has checked into a rehab facility for anger management issues. Brown was dropped off to the facility yesterday by his attorney, Mark Geragos.

Brown was arrested in DC over the weekend after allegedly punching a guy in the nose. The L.A. County probation department is doing the maximum in its investigation to determine if Brown had violated his probation in the Rihanna case.

TMZ sources suggest that Brown flew off to L.A. after getting released from the D.C. jail and met with L.A. County Probation Department officials. Sources also report that his mom and GF Karrueche accompanied him to the facility.

If the judge decides Brown violated his probation, he could sentence him to as much as 4 years in prison.
