ATLANTA (AP) — School officials in Atlanta say metal detectors weren’t working at Price Middle school when a 14-year-old student was shot and wounded there.

The Atlanta Journal-Constitution reports public school administrators acknowledged in a statement late Friday that the school’s two metal detectors were “not operable” Thursday. The statement said an investigation found there had been limited use of the detectors at the school this year.

Atlanta police say they suspect the shooting, which happened in the school’s courtyard, may have been gang related. A 15-year-old boy has been arrested. The boy who was injured was treated and released from a hospital.

Atlanta Public Schools officials say they plan to immediately test all school metal detectors and review student entrance and exit procedures.
