HICKMAN, Neb. (AP) — Authorities say 30 horses have been rescued following an early morning fire at a barn near Hickman.

The Lancaster County Sheriff’s Office says the fire at the 13,600-square-foot Still Waters ranch began shortly after midnight Monday. First responders were able to get the horses out of the arena and stables, which did not catch fire.

The front part of the barn and a tack room was fully engulfed in flames when authorities arrived.

Lancaster County Sheriff Jerry Wagner says investigators believe an electrical malfunction caused the fire. Damages are estimated at $300,000.
