Eleven people were displaced in a fire at a multi-family home at 111 Maple St. in Killingly early Tuesday morning, but no one was injured.
Mutual aid was called in and firefighters arrived to find flames shooting from the window of the second floor.
Crews had trouble pulling up the floors because hardwood floors were put over the existing flooring, so everyone was called out for safety concerns and the fire spread to third floor and attic, officials said.
"The floor was covered with hard wood, so they couldn't pull ceilings and that type of thing. We had mutual aid come in from nine other departments and supplement our people. By that time, the fire had broken through the roof, and we pulled everybody out," Danielson Fire Chief Gerald Marcheterre said.
