Halifax Police have charged a teenager in relation to an incident Wednesday at two schools in Dartmouth. Police were called to Dartmouth High School on Victoria Road around 10:30 a.m after a threat was made to one of its students.

The Halifax Regional School Board says a girl at the school notified administration that a student had received threatening text messages from someone who isn’t a student at the school.

Dartmouth High and nearby Bicentennial Junior High were placed in hold-and-secure. Students were told to stay in their classrooms with the lights off while police searched for the man.

An 18-year-old was arrested at a nearby gas station on Main Street without incident. He’s facing charges of public mischief and is expected to appear in court at a later date.

The lockdown ended around 11:30 a.m. and lasted for about half an hour.
