Rappers Chris Brown and Drake are involved in a violent bar brawl at the club W.i.P. (Work in Progress) in Manhattan's SoHo neighbourhood early on Thursday that injured at least five people.

In the fight, a 25-year-old man suffered a severe cut on the head, two men and two women suffered minor cuts. At least three of the victims were hospitalized.

Chris Brown tweeted a photo of himself with a cut on his chin and other tweets about the altercation. He tweeted, How u party wit rich n----- that hate? Lol... Throwing bottles like girls? #shameonya!." However, the rapper later removed the tweets.

Brown's representative said that the rappers and their entourage were the victims of the violent brawl. "Chris and his party are co-operating with NY authorities who are pursuing this incident further," Brown's representatives wrote in a statement.

There are reports that the fight started when the singers were fighting over Rihanna, who used to date Brown and later dated Drake.

Police are now looking at the surveillance footage as well as talking to the patrons who witnessed that brawl. The police arrived at the scene later but the rappers already fled. Thus, no arrest was made.

Brown had a violent relationship with Rihanna and is still on supervised probation for attacking her on the eve of the 2009 Grammy awards, leaving her with a split lip, a black eye and other injuries.
