Sheriff's deputies facilitated a controlled dismissal of South Carroll High School on Wednesday afternoon after the school was placed on lockdown after a nonspecific threat just before the end of the school day.
School officials received a phone call at about 2:25 p.m. Wednesday, according to a news release from the Carroll County Sheriff's Office.
Buses had arrived at the school and some parents had arrived to take students home, according to Sheriff Jim DeWees. Deputies established a perimeter and conducted a quick sweep of the interior and exterior of the school.
"I think it was handled appropriately based on the information we got," DeWees said.
A small group of students who drove themselves to school were mistakenly dismissed during the lockdown, DeWees said, but deputies were able to take them to a secure location in the school until the scan was completed.
