They say a youth was receiving treatment for injuries after an incident involving an edged weapon took place early yesterday on school grounds.
The injuries sustained were described as minor.
RCMP say all parties involved are known to each other and police do not believe there to be any risk to the public.
They say they are working closely with the School District and Partner agencies to provide the best possible support for families involved.
