The assault unfolded at the Miami International Airport, when the woman and the cop began arguing, according to a video of the incident filmmaker Billy Corben posted to Twitter.
It’s unclear what sparked the dispute, but the video begins as the woman steps up to and shouts at the officer.
“You’re black. You’re acting like you’re white but you’re really black,” the woman can be heard saying to the officer — both of whom are black.
“What are you going to do?” the woman adds.
The officer then cocks back his fist and punches the woman as bystanders gasp.
A second cop standing nearby then joins to assist the first officer as they grab the woman and pin her down as they place her under arrest.
The director of the police department, Alfredo Ramirez, announced about 30 minutes after the video was posted that the department has launched an investigation into the officers’ conduct.
“I am shocked and angered by a body cam video that I just saw involving one of our officers. I’ve immediately initiated an investigation and ordered that the involved officers be relieved of duty,” Ramirez said in a tweeted statement.
“Actions such as these undermine the hard work that we have invested in our community and causes my heart to break for our community and for the vast majority of our officers who dedicate their lives to serving our County,” Ramirez went on.
The director said he has also requested State Attorney Kathy Rundle to assist in the investigation into the involved officers, who have not been identified.
“This will not stand, and I assure our community that any officer acting in this vain will be held to account,” Ramirez said.
