A fire caused the evacuation and temporary closure of a Walmart store in north Bismarck on Friday and city officials say early signs indicate the fire may have been set intentionally.

Authorities say the fire was reported around 8 AM. Crews extinguished the fire in the garden center, which sustained fire and smoke damage, but damage was limited because of the building’s sprinkler system.

A Walmart employee said the store should re-open on Saturday.

Eighteen firefighters were on the scene. No injuries were reported.

The cause of the fire is under investigation.
