The Valhalla Fire Department assisted North White Plains Fire Company No. 1 at the scene of a structure fire yesterday morning. Crews worked to extinguish a fire that started outside the house and extended into the house. Crews had to open up the roof due to the fire spreading into the attic space. The fire was quickly brought under control. Other units on scene included Thornwood Fire Department, West Harrison Fire Department, and Valhalla Ambulance Corps.
