Bobby Shmurda repped the Crips in prison brawl last month in New York City's Otis Bantum Correctional Center.

Law enforcement sources tell TMZ that they came upon a fight involving Shmurda, three other Crips and two Bloods. They broke it up with a "pepper spray-like" chemical agent.

Among the combatants were an accused murder, a burglar, a kidnapper and sodomist. No word if Bobby's boy Rowdy Rebel was involved, or if Shmurda was punished for his role in the melee.

Shmurda and Rebel's trial on weapons and drug charges is set to begin on June 25th. Shmurda maintains he is innocent and the cops are out to get him because of his success.
