Columbus Police Officer Zachary Rosen is under investigation after video footage has been released showing him kicking a restrained man in the head. He’s been placed on “non-patrol duty,” according to NBC.

It was later revealed that Rosen was also one of the officers who was under investigation – but ultimately never indicted – for the 2016 shooting death of Henry Green.

Rosen was one of the officers to arrive on the scene after police received a call that a man was threatening to “shoot up the house and everyone in it.” Reports state that Demarko Anderson then fled from the officers and was later apprehended.

A video posted to YouTube then shows an officer enter the frame shortly after the 25-second mark and kick Anderson in the head despite him being on the ground with an officer on top of him.

“The guy was on the ground already. He already had restraints on him. What is the point of continuing to stomp him out on his face? What was the point of that? There is no need. You already got him down. He can’t move. He can’t do anything else,” said Kanyinsola Oye, a social justice activist. “That seems more like a fight like you’re trying to hurt someone, to me.”

The Columbia Police Department released a brief statement on the incident and explained that Rosen has been reassigned.

“Based on what we see in the video taken on Saturday April 8, 2017, the action taken by one of our officers does not meet the standards by the Columbus Division of Police,” reads the statement. “It appears to be inconsistent with the values and training we instill in our officers.”
