No injuries were reported in a Friday morning fire at a commercial building on Chicago's northwest side.
The fire, at 1945 N. Latrobe Ave., was in a warehouse used by Advanced On-Site Concrete Inc.
It took a little more than an hour for crews to extinguish the fire. At one point, the roof of the one-story structure collapsed as firefighters doused it with three streams of water.
Caution was taken because firefighters were advised the building contained propane tanks. The building was considered by fire officials to be a total loss.
Metra trains traveling nearby were temporarily halted.
