Crews responded to the scene of what one agency referred to as a 'major structure fire' in Casco Friday night. Cumberland County dispatchers confirm nobody was hurt. The fire at 11 Varney Hill Road was reported just before 5:30 p.m. but it was unclear if anyone was inside the building when the fire broke out. Firefighters and trucks from multiple surrounding communities were called to help either at the scene of the fire or to provide mutual aid coverage. The Chief of Casco Bay Fire Department is now investigating the cause of the fire.
