LOCHEARN, Md. (WJZ) — Baltimore County Police said three people were arrested after threats were made against a student at Sudbrook Magnet Middle School Wednesday afternoon.

While investigating a series of threats made on social media, officers said they found a car around 4 p.m they believed was involved in the threats. The occupants of that car were arrested.

The middle school and Bedford Elementary School enacted a lockout during the investigation. No injuries were reported, but an investigation is ongoing.

A lockout occurs when a possible threat is outside a school, while a lockdown happens when a threat may be within a school.
