A significant three-alarm fire erupted Friday night at an unoccupied apartment complex under construction in Denver, near Leetsdale Drive and South Forest Street. Firefighters battled the blaze for hours, with heavy smoke and flames visible for miles. The unoccupied nature of the building allowed crews to focus on containment, and no injuries were reported. The cause of the fire is under investigation, and the incident led to road closures and power outages in the surrounding area.
