The Denver Fire Department told ABC News that one firefighter was injured while battling the blaze and was taken to the hospital.
No other injuries were reported.

By early evening, the fire was largely under control but had not yet been completely extinguished. Officials estimate the fire is about 70% contained, with some deep fire still burning inside the building. Firefighters are expected to remain on scene throughout the night to fully extinguish hot spots.
