Some witnesses have reported hearing shots during the dustup Thursday morning at W.i.P in SoHo, but no one reported seeing a gun. Police are looking into the claims.

Chris Brown, his girlfriend and his bodyguard were among eight injured during the fight inside the club. Police say members of Drake's entourage stopped Brown as he was leaving. The fight escalated and bottles were thrown.
