Zul-Qarnain Kwame Nantambu is a 41-year-old New Orleans-based activist, jeweler, and performer known for his involvement in high-profile incidents.[1][2] He gained public attention through a 2022 dispute with former NFL player Antonio Brown, whom he met at an exhibition fight in Dubai. Nantambu allowed Brown to wear a $122,000 custom diamond pendant, which Brown allegedly failed to return, leading to Nantambu's month-long arrest in Dubai before his release and a lawsuit that initially awarded him $970,000 in damages, later overturned on procedural grounds.[1] In May 2025, Nantambu was the victim in a shooting outside a Miami celebrity boxing event, where Brown was charged with attempted murder after allegedly firing at him and grazing his neck during a struggle over a gun.[1][5] Nantambu described fighting for his life amid the altercation.[1] Nantambu drew further scrutiny for his role as an extra performer in Kendrick Lamar's Super Bowl LIX halftime show on February 9, 2025, at New Orleans' Caesars Superdome. Authorized to be on the field, he deviated by displaying a Sudanese flag reading "Sudan and Free Gaza," running across the field, and ignoring security commands to stop, disrupting the performance.[2][4][5] On June 26, 2025, he surrendered to Louisiana State Police on charges of resisting an officer and disturbing the peace by interruption of a lawful assembly; the investigation continues.[2][5] These events highlight Nantambu's activism on issues like Sudan and Gaza, alongside his jewelry work and performance appearances, though they have resulted in legal entanglements.[1][2] No additional professional roles or achievements beyond these are detailed in available reports.[3]
