A store surveillance video obtained by a TV station shows a man violently swinging a flagpole at a Louisville Metro Police officer before police say the officer fatally shot him.

Police say the officer responded to an assault call Saturday in Old Louisville. The video WHAS-TV says it got from a nearby smoke shop shows the officer talking briefly with the man, who seems to become agitated and walks away from the officer.

The video, broken down into segments, then shows the man advancing toward the officer and swinging a flag pole at the officer. At one point the flag pole breaks.

The video shows the officer pointing his gun at the man, but doesn't show him firing.

Police have declined to identify the slain man or the officer.
