School resource officers and Bridgeport police began looking for the student and placed the school on lockdown. Police quickly took the girl into custody and changed the lockdown to a lock out. The lock out was lifted by 2:39 p.m.
Police say the weapon was identified as a pellet gun. The girl was taken to police headquarters where she was charged and later released to her guardian.
Police have not disclosed what charges the girl faces.
