A 15-year-old male could face charges of uttering threats after Cowichan Secondary School in Duncan received an online threat Friday morning.
North Cowichan/Duncan RCMP are investigating the incident that locked down the high school on James Street around 11 a.m.
Police say a student of the school notified staff after seeing the online threat and a lockdown procedure was activated and a call went to the RCMP.
The suspect youth is not a student at the school and was located a few blocks away and arrested without incident.
The school has reopened and in a statement, Cowichan Secondary School says all students and staff were safe inside during the lockdown.
The school says they were notified after a short time by police there was no longer a concern for safety, allowing the lockdown to be lifted and classes to resume.
Counselling supports are available for the students as needed.
