SCOTTSBLUFF, Neb. (AP) — Authorities say space heaters caused a fire at a Scottsbluff house.

The Scottsbluff Fire Department says an overuse of space heaters caused an electrical overload in the house’s attic, leading to the Wednesday morning fire.

Nearly two dozen personnel from two fire departments responded to the scene. Smoke could be seen coming from the second floor. Flames also broke through the house’s roof.

Fire crews were able to contain the blaze. No injuries were reported, though four people have been displaced.

Damage from the fire has been estimated at up to $35,000.
