According to the Associated Press:
A 20-year-old man accused Brown of punching him after he tried to get in a photo with the R&B singer.
Brown denied to police that he hit the man but was charged with misdemeanor assault.
Since then, the Grammy-winner has entered and left rehab for anger management treatment.
Brown’s probation for assaulting Rihanna was briefly revoked this summer after a hit-and-run incident. He was also ordered to redo 1,000 hours of community service because there were questions about whether he actually completed his initial penalty.
If Chris Brown is found guilty regarding the incident in Washington D.C., his probation will be revoked. He could spend up to four years in prison
