Four males checked out the Humboldt Museum and Gallery on July 14th, but it wasn’t during regular hours.
Humboldt RCMP say the four gained access to the fire escape stairs at the back of the building between 1 and 2 that morning.
They trespassed into the building and onto the rooftop.
There was no damage done and no one was injured.
Pictures from the security video indicate they may be in their late 20s.
Anyone with information can contact the RCMP or Saskatchewan Crime Stoppers.
