Morley Stanwood Community Schools were locked down after a threat was made to an employee and building of the district.
According to the district's Facebook page, the situation has been resolved and the schools are no longer locked down.
According to the Mecosta County Sheriff, deputies were informed that a student was upset yesterday at school, went on Facebook and made threats to do damage to the building.
The school found out about the threat this morning.
The suspect was arrested on an unrelated charge. The Sheriff's Department is still investigating the threat complaints.
The name is not being released at this time.
The buildings were on an external lock down which means external doors are secured, but people are allowed to move around the building with permission.
WOOD-TV reports the lock down drill that was scheduled to occur Thursday morning is not related to this incident.
