A 14-year-old student was shot in the head at a middle school in Atlanta on Thursday afternoon.

Police descended on Price Middle School just south of downtown Atlanta after reports of the shooting at 1:50 p.m. Televised helicopter images on local news reports showed a crowd of frustrated parents gathering outside the campus waiting to hear about the safety of their children.

Students were being kept at the locked-down school some two hours after the shooting but television footage showed some of them being dismissed.

Atlanta police spokesman Carlos Campos said the wounded boy was transported “alert, conscious and breathing” to Grady Hospital. It’s thought his injuries are not life-threatening.

Atlanta Public Schools said on their website that the suspect, who has been taken into custody, was a student. Calls to the school district were not immediately returned.
