MIAMI (AP) — Early Saturday, former NFL player Antonio Brown was momentarily held by police after a dispute occurred involving gunfire outside a celebrity boxing match in Miami, as reported by Brown himself and seen in social media videos.

The Miami Police Department confirmed through a statement that they responded to the scene at around 3 a.m., following an alert from ShotSpotter, the gunfire detection system. Officer Kiara Delva noted that police interviewed multiple individuals but did not make any arrests. There were no reported injuries at the location.

The investigation continues, Delva said, and she could not confirm the names of anyone involved.

Social media footage showed Brown engaged in an altercation with others at the boxing event organized by well-known streamer Adin Ross. During the incident, Brown appeared to be holding a black handgun while chasing somebody. Gunshots were heard off-camera shortly after.

Additional video showed Brown, hands behind his back, being escorted from the venue by an officer.

Brown posted on social media that he had been “jumped by multiple individuals who tried to steal my jewelry and cause physical harm to me.”

“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,” Brown wrote.

Brown’s statement did not mention the gunshots.

Brown played for the Pittsburgh Steelers from 2010 to 2018, where he emerged as one of the NFL’s top receiving threats and twice led the league in receiving yards. His career took a downturn because of various on- and off-field issues, including his contract being voided by the Oakland Raiders before the start of the 2019 season.

He split his final three NFL seasons with New England and Tampa Bay, and his career ended with Brown stripping off his jersey, pads and gloves, while walking off the field during the Buccaneers’ 2021 regular-season finale against the New York Jets. Brown announced his retirement a few months later.
