The Miami Police Department is investigating video of a police officer seemingly punching a handcuffed man that has gone viral since being posted to Facebook.

In the video, the officer can be seen arresting a man and putting him in the back of a police car before he seems to begin punching him.

The woman who took the video posted it to Facebook but asked not to be identified because the officer had ordered her to delete the video.

“We have seen the video and we have launched a full internal affairs investigation into the matter,” Maj. Delrish Moss said in a statement. “We take that responsibility very seriously.  The officer involved in the incident will be relieved of duty as we investigate.”

“As everyone is aware, social media has placed a very negative tone on law enforcement nationwide,” Lt. Javier Ortiz, president of the Miami Fraternal Order of Police, said in a statement. “While the video may seem disturbing to some, the FOP is convinced that when everything is analyzed within the totality of the circumstances, it will be concluded that the police officer was doing what he is supposed to be doing — protecting our community.”

When reached for comment, the man in the video said, “The video speaks for itself. I don’t really have nothing to say.”
