A white police officer shot and killed an unarmed black man at an apartment complex in Chamblee, Ga. Monday afternoon. The man has been identified as 27-year-old Anthony Hill; he is believed to have suffered from mental illness.

Officers were called to the The Heights at Chamblee apartment complex, police told reporters, after Hill was reported "acting deranged, knocking on doors and crawling around naked."

When police arrived at the scene, Hill reportedly charged at an officer, who after stepping back and warning him to stop, opened fire, shooting Hill twice. Hill died at the scene.

DeKalb County Public Safety Director Cedrid Alexander told Fox Atlanta that it's "likely mental illness played some role in Hill's behavior."

Alexander also told the New York Times that the officer, who has since been placed on administrative leave, also had access to a Taser and pepper spray.

An investigation into the shooting has been launched by the Georgia Bureau of Investigations.
