KALISPELL, Mont. (AP) — Authorities are investigating after someone broke into the Smith Valley fire hall and set fire to a rescue truck that caused extensive damage.

The truck was a total loss and a nearby engine had serious damage, which could slow response to emergency calls in the area.

Fire Chief D.C. Haas of the Smith Valley Fire Department says a door was kicked in and someone set the fire. As of Sunday afternoon, no arrests had been made.

The Daily Inter Lake reports (http://tinyurl.com/hv6j4v7 ) six sets of firefighting gear for fighting building and wildland fires, along with Jaws of Life equipment to pry victims from wrecked cars, water rescue equipment, a defibrillator and other important emergency equipment were destroyed at the busy station.
