The Huron Detachment of the Ontario Provincial Police (OPP) is investigating an incident that prompted a "hold and secure" at the high school in Wingham on Monday morning.
Just before 9:00 a.m., police were called about a threat allegedly made by a high school student toward another student.
A "hold and secure" of F.E. Madill Secondary School in Wingham was activated by school officials while staff and police searched the property for a suspect.
Investigators were able to locate a suspect, who was arrested shortly after.
The "hold and secure" has since been lifted, and there is no threat to public safety.
Any person with information regarding this incident or any other incident is asked to contact Huron OPP at 1-888-310-1122 or (519) 482-1677.
