Kawartha Lakes OPP were contacted by a student's parents last week after it's alleged the student was threatened by another, while riding the school bus on their way home from school.
The students involved attend Ridgewood Public School in Coboconk.
A Trillium Lakelands District School Board rep advised that while they will not discuss anything about a particular student or situation, the safety of their staff and students is their first priority.
The school board says they have safety protocols in place as well as a Code of Conduct policy outlining conduct expectations and incidents are responded to appropriately.
The investigation is on-going.
