The "Don't Wake Me Up" singer allegedly attacked and began punching a man outside the W Hotel, the site reports. The incident occurred at around 4:30 a.m.
It appears that law enforcement does not believe that Brown was under the influence at the time, and he is currently in custody. The man attacked is now at a nearby D.C. hospital being evaluated.
The "Forever" singer is currently on probation for beating his now ex-girlfriend Rihanna in 2009 on the night before the Grammy Awards. During a recent interview with the UK Guardian, Brown opened up about "the Rihanna incident."
"I had to stop acting like a little teenager, a crazy, wild young guy," he said during the interview. "But at the same time, I learned from it, and it was almost like...I wouldn't say it happened for a reason, but it was something to trigger my mind to be more of a mature adult. To handle myself in situations, don't throw tantrums, don't be a baby about it."
On Aug. 16, Brown was also sentenced to complete 1,000 more hours of community service. The Los Angeles District Attorney accused the entertainer of fudging his community service hour records stemming from a hit-and-run accident in May.
