Chatham-Kent police have laid a second charge stemming from an investigation into a knife brought to a Chatham secondary school.
The student, who was arrested at John McGregor Secondary School, was charged but he told police the knife was for protection, because he had been threatened on Facebook.
Chatham-Kent police began searching for the man who allegedly made the threats; a 19-year-old with no fixed-address.
He's charged with uttering a threat and was held in custody for a bail hearing.
