A North Carolina officer submitted his resignation on Wednesday after the policeman was seen on video yanking his K-9 partner by the leash and violently tossing him into the back of a cruiser.

The Salisbury Police Department identified the handler as officer James Hampton and concluded that he “acted in a manner entirely inconsistent” with his training and in violation of policy, authorities wrote in an announcement. Hampton, who was recommended for termination, tendered his resignation prior to a due process hearing by the department.
