Officials are trying to determine what sparked a fire at a Cheyenne concrete plant late Wednesday night.

Cheyenne Fire Rescue spokesman Scott Smith says firefighters were called to a possible tree/trash fire in the area of 819 E. 15th Street shortly after 10 p.m.

Upon arrival, they discovered an old storage building at Croell, Inc. fully engulfed in flames.

Crews were able to keep the blaze from spreading to adjacent buildings, and had the fire out in about 45 minutes.

Smith says no one was injured in the fire.
