Antonio Brown is under arrest and back in the United States ... about six months after the former NFL superstar was accused of trying to shoot and kill a man at an Adin Ross boxing event in Florida.
TMZ Sports is told 37-year-old AB was extradited this week, with United Arab Emirates authorities shipping the retired wideout back to the States from Dubai, where he was allegedly attempting to evade the reach of the American legal system.
We're told Brown was accompanied by federal agents to New York City, where he was turned over to local police, who arranged for him to be sent back to South Florida, where the incident went down.
