Brown, 24, was involved in a fight with an adult male at around 4:25 am on Sunday morning outside the hotel. The person claimed he sustained injuries, the Hollywood Reporter said quoting a metropolitan police spokesperson.
The singer and Chris Hollosy, 35, were arrested and charged with felony assault.
Brown was in Washington to play "the biggest homecoming party" at nightclub The Park along with artist August Alsina. The venue billed it as a "Grand Finale Event."
It is not for the first time that Brown has faced legal woes. He was sentenced to community service after his involvement in a hit-and-run accident in August.
He was also involved in a scuffle with Drake and his entourage last year in New York.
