LAWTON, Okla. (AP) — Authorities say a Lawton man who police fatally shot emerged from his apartment holding two butcher knives and then charged the officers, cutting one.

Police in Lawton released an incident report that identifies Millard Clark Jr. as the man who was killed. The Oklahoma State Bureau of Investigation is looking into the shooting in Lawton, about 90 miles (145 kilometers) southwest of Oklahoma City.

The report says officers James Carr and Christopher Blessing were called to an apartment Tuesday on a disturbance report. Clark was standing in the apartment doorway holding the knives when they arrived. Officers tried to talk to him but he became increasingly angered and charged at them, cutting Carr.

An OSBI agent has said the officers used a stun gun on Clark before firing their guns.
