Antonio Brown is wanted in Florida, after cops say he stole a security guard’s gun and tried to kill a man outside of a celebrity boxing match last month.

TMZ Sports has obtained the arrest warrant that was issued this week for Brown … and in it, there all kinds of troubling allegations against the former NFL superstar.

According to the document, Brown and Zül-Qarnaįn Nantambu were seen on surveillance video getting into an argument near Adin Ross‘ May 16 Brand Risk event in Miami, before Brown could be seen hitting Nantambu with “a closed fist.”

According to the document, Nantambu said in an interview with police on May 21 that Brown did shoot at him following their physical altercation … and one of the bullets possibly grazed him in the neck. Cops wrote Nantambu had “visible injuries.”

As you know, police did initially respond to the incident and did detain Brown briefly at the scene. They noted in the arrest warrant he did not have a gun on his person … and after they could not find a victim at the scene, they let him go.

The warrant states Brown is wanted on one felony charge of attempted second-degree murder with a firearm. It also notes he will be required to post a $10,000 bond while remaining under house arrest as he awaits trial.

For Brown’s part, he said in a statement following the incident on May 17 he “was jumped by multiple individuals who tried to steal my jewelry and cause physical harm to me.”

“Police temporarily detained me,” he added, “until they received my side of the story and then released me. I WENT HOME THAT NIGHT AND WAS NOT ARRESTED.”

Antonio Brown is wanted for attempted murder, TMZ can confirm.

Law enforcement sources tell us authorities in Miami-Dade County, Florida are seeking to arrest the former NFL wide receiver on a charge of attempted murder stemming from a shooting at a celebrity boxing event in May.

We covered the incident — AB was briefly detained by police following an intense dust-up involving a gun at Adin Ross‘ Brand Risk kickboxing event just over a month ago.

Video obtained by TMZ shows him getting into a physical altercation with men he claimed tried to jump him and steal his jewelry … and another clip shows him fleeing the scene with what appears to be a gun in his hand — before clear gunshots are heard ripping through the air.

Zül-Qarnaįn subsequently told TMZ Sports he was one of the men involved in the scuffle with Antonio … further claiming he unloaded some bullets right at him  — with kids around during the incident.

Now, David Ovalle of the Washington Post is reporting an unnamed victim met with law enforcement and claimed AB opened fire at him following the physical altercation, which prompted the warrant for his arrest.

David also reports the warrant will require a $10,000 bond and the sports star to remain under house arrest pending trial.

TMZ reached out to a rep for Antonio for comment … so far, no word back.
