Assumption College High School was on a brief hold and secure Tuesday afternoon, after a man was seen in the area with a knife.

Students from the school witnessed the suspect holding the knife, that’s when they ran back to the campus and informed the principal. Assumption was then placed on a hold and secure for about an hour, while an investigation was conducted.

Windsor police says at no point did the suspect enter the school, nor was anyone injured.

Through their investigation, officers located a knife in the area. The suspect was discovered a short time later, where he was arrested.

Police wouldn’t say if charges have been laid.
