Two people were left homeless Thursday after fire and smoke caused heavy damage to their ranch home on Bath Road in Brunswick.

One of the occupants was at home when fire broke out in a bathroom ventilator fan around 12:40 p.m. The man fled from the home at 433 Bath Road.

Hunter said the fire spread from the bathroom to the attic, forcing firefighters to cut holes in the roof. The cause of the fire, which does not appear to be suspicious, remains under investigation.

The Maine Chapter of the American Red Cross responded and crews from Brunswick and Bath fought the fire.
