Last night, gunfire broke out backstage right before T.I.'s set at New York's Irving Plaza.

Four people were shot, with one fatality -- Troy Ave's bodyguard Ronald (BSB Banga) McPhatter. Troy had his leg grazed and is expected to recover.

Maino and Uncle Murda were on stage at the time of the shooting and the police are investigating whether a dispute between the crews of Maino and Troy Ave sparked the incident.

New York Police Department Commissioner Bill Bratton kicked up some controversy this morning by labeling rappers "thugs" when addressing the incident.

“The crazy world of the so-called rap artists who are basically thugs that basically celebrate the violence they live all their lives and, unfortunately, that violence often manifests itself during the performances and that’s exactly what happened last evening,” Bratton said during a radio interview this morning on WCBS 880.

Update: Maino denies he had anything to do with the shooting:

First and foremost my deepest condolences to the family & friends of Ronald Mcphatter who was tragically killed last night. Despite having to cope with more senseless violence. I woke up to the usual FALSE and ridiculous lies being circulated by irresponsible members of the media. What transpired was absolutely NOT the result of MYSELF or ANYBODY IN MY CAMP , ENTOURAGE, TRAVELING PARTY or ORGANIZATION IN ANY WAY SHAPE OR FORM. We entered the venue respectfully as always and exited in shocked like all other concertgoers. For the last 5 years Troy Ave, his team and I have had a great working relationship. Not only have we performed and done several songs together but we've had many personal conversations about life our goals and efforts as musicians. Despite media reports to the contrary, there are No "ongoing beefs" or "entourage issues." It always has been and always will be good relations between myself AND MY TEAM and @TroyAve @Hovain @YoungLitoBsB and the BSB crew. Our deepest sympathies again to family of Ronald McPhatter and a speedy recovery to Troy Ave. The movement will not be stopped. #BROOKLYNUNITED #HEARDYOU
