A U.S. Army sergeant is suspected of shooting and wounding five fellow soldiers with his personal handgun on Wednesday at Fort Stewart Army Airfield near Savannah, Georgia, before he was subdued by other soldiers and arrested,

Gunfire erupted at Fort Stewart in Georgia on Wednesday morning, prompting the base commander to lock down facilities in the wake of this “active shooter” incident.

The suspect has been identified as Quornelius Radford, an automated logistics sergeant assigned to the base, said Major General John Lubas, commanding general of the Army’s 3rd Infantry Division. Radford reportedly used a personal handgun to open fire on fellow soldiers.
