Former NFL star Antonio Brown is accused of trying to kill a man with a gun he took from a security staffer outside a boxing event in Miami, according to a newly released warrant.

Antonio Brown faces an arrest warrant for attempted murder following an alleged shooting during a celebrity boxing event. Zül-Qarnain Nantambu claims Brown attacked him over a long-standing dispute stemming from a Dubai incident involving stolen jewelry.

Brown is being sought by police for his role in a brawl outside of a May 16 boxing event in which he allegedly fired a gun.
