A Salemwood School student was arrested Friday after school officials discovered he had carried a knife onto school campus.
The child, a minor, will not have his identity released to the public.
Lt. Det. Marc Gatcomb of the Malden Police Department said there were "no students in danger by any means, and no talks of lockdown."
This is the second child discovered bringing a knife onto campus in a month - in December, a similar incident was reported in Linden School.
