LANHAM, Md. (CBSDC) — A series of bomb threats at Leonardtown High School and two nearby court buildings caused evacuations Thursday morning.
The school was placed on lock down after a phone threat was received around 8:10 a.m., the St. Mary’s County Sheriff’s Office says.
The Circuit Court building, which had been evacuated, reopened around 9:30 a.m. after a search of the building revealed no threat, authorities say. The District Court building remained open under the order of a judge, according to the sheriff’s office.
The school remained locked down until around 10:40 a.m. when bomb-detecting K9 units completed a search of the premises without discovering a threat, officials say.
Authorities from St. Mary’s, Calvert and Charles counties were used to search the three locations.
The St. Mary’s County Sheriff’s Office has since ruled the threats as a false report from an unknown male subject. Authorities continue to investigate the source of the threat.
