At approximately 4:30 a.m. today a 911 call came in to the Portage Fire Department about a structure fire on 1st Street SW in Portage la Prairie. Crews arrived on scene to find the house ablaze, with flames emitting from the south side of the building. Flames were quickly extinguished, but due to the older construction of the house fire went inside the walls and ceiling. One truck remained on the scene to ensure the fire not start up again. The home was vacant and no one was harmed. The fire is considered suspicious and is currently under investigation.
