Columbus, Ohio, police officer Zach Rosen was fired last summer after he was caught on video stomping on a handcuffed suspect causing his head to strike the pavement in April 2017. But the Columbus Division of Police has since reinstated Rosen according to an announcement on Monday, The Columbus Dispatch reported.

Columbus Public Safety Director Ned Pettus opted to fire Rosen in July 2017, with the support of the Columbus City Council and Mayor Andrew Ginther at the time, WOSU reported. Pettus's decision overrode Columbus Police Chief Kimberley Jacobs's recommendation to suspend Rosen for 24 hours, or a three-day suspension. 

Rosen has since been reinstated by an arbitrator according to a 27-page decision issued Monday and obtained by The Dispatch. Sgt. Dean Worthington, a spokesperson for the Columbus Division of Police, told The Dispatch that Rosen will undergo training before returning to patrol work. 

The arbitrator who issued the decision, Mitchell B. Goldberg, said Rosen used an "untrained technique" since he had "less-excessive force options available to him," when he stomped on suspect Demarko Anderson. 

"…Moreover, I find from the evidence, that because the Grievant had other less-excessive force options available to him, his use of an untrained technique amounted to excessive force that was a violation of policy, directives and the law," the document read. 

But he later added that Rosen's "past good work record" proved he had the ability to "adjust his actions to conform with policies and directives in the future as they relate to his use of force in bringing dangerous suspects under control." 

According to The Dispatch, Ginther's office issued a statement expressing disappointment in the decision to reinstate Rosen.

"We disagree with the decision of the arbitration of Columbus police officer Zach Rosen," the statement read. "We believe the public safety director’s decision for termination was the correct one. However, we respect and will abide by the legally-binding arbitrator’s decision.”

The Columbus Division of Police has not immediately returned Blavity's request for comment.
