Portage RCMP have now made an arrest following Tuesday's morning's fire in the city that officials deemed suspicious.
Police responded to the fire around 3 a.m. on March 2, and arrived to find the house completely engulfed in flames. The fire took over three hours to extinguish.
Several families lived in the building, and all occupants were able to evacuate safely.
A 24-year-old woman from Portage faces charges of assault with a weapon, uttering threats, and being unlawfully in a dwelling.
Investigators determined she started the fire by igniting items on the porch of the home, according to police.
She remains in custody and is now also charged with arson with disregard for human life and arson with damage to property.
Police will not be naming the suspect as there are concerns for her safety.
