SPARROWS POINT, Md. — Sparrows Point Middle and High Schools were placed on a brief lockdown Thursday morning.
The emergency was prompted by a loud noise that some mistook for possible gunshots.
According to a school letter sent to student parents, "the loud noise came from a vehicle that backfired."
The lockdown was implemented at 10:50am, and lifted at 11:29am, per Baltimore County school officials.
As per school policy, no one is permitted to enter or leave the building during a lockdown.
Protocol requires classes to be paused and students and staff to remain in a secure location throughout.
