Former NFL wide receiver Antonio Brown was detained following an altercation that took place outside a celebrity boxing event in Miami early Saturday morning.

Police in Miami, Florida, confirmed in a statement on Saturday that several people were questioned after gunshots were fired during an altercation at a boxing event hosted by Adin Ross. Miami police spokesperson Kiara Delva said officers responded to the area at around 3 a.m. ET after receiving an alert from the gunshot-detection system ShotSpotter, according to The Associated Press (via ESPN).

The AP noted that videos that circulated on social media allegedly showed Brown in a fight with several people. It appeared Brown was holding a firearm as he pursued someone, and several gunshots could be heard.

Delva said the investigation remains open and that she could not reveal the identities of anyone involved. Brown addressed the incident with a post on X.

Brown said he was attacked by multiple people who tried to rob him.

“Regarding the boxing event that happened last night. I was jumped by multiple individuals who tried to steal my jewelry and cause physical harm to me,” Brown wrote on X. “Contrary to some video circulating, Police temporarily detained me until they received my side of the story and then released me. I WENT HOME THAT NIGHT AND WAS NOT ARRESTED.

“I will be talking to my legal council and attorneys on pressing charges on the individuals that jumped me. I will keep you all posted step-by-step on the process.

“Thank you for the support and love.”
