Troy Ave has filed a lawsuit against New York City concert venue Irving Plaza, in which he blames poor security for a gunfight at T.I. concert in May that left his friend dead.

According to PIX 11, Troy Ave alleges that Live Nation, the conglomerate that owns Irving Plaza, had relaxed security measures that allowed a gun to enter the venue.

Surveillance footage from the incident captured Troy Ave firing a gun; while he was initially charged with attempted murder, that charge has been dropped. He is still facing numerous serious charges. His attorney, John Stella, is arguing that he took the gun from the man who killed his friend, Ronald McPhatter, and returned fire.

Troy Ave is currently free on $500,000 bail. He is forbidden from visiting clubs, bars, arenas, and stadiums,
