Police in Moose Jaw are investigating some vandalism at the former Ross School building.
According to police around 4:00 p.m. on Saturday some kids got inside the building by breaking in through an unsecured door.
Police said while the kids were in the building they skateboarded around and set off fire extinguishers.
The school was originally closed in 2007 but has since been converted into office space.
The building currently has no tenants.
