The singer filed an assault and battery lawsuit Wednesday against Sha'keir Duarte, who claimed in an earlier suit that he was injured when a fight erupted between Brown and Frank Ocean's entourages in January outside a West Hollywood studio.
Duarte's lawsuit filed in August accused Brown of being the aggressor in the fight. Brown's countersuit however accuses Duarte of instigating the fight by pushing, kicking and punching the R&B singer and threatening to kill him.
No criminal charges were filed over the fight. Brown's lawsuit seeks unspecified damages.
Duarte's attorney Joseph Porter III did not immediately return a phone message seeking comment.
