Here's a report from Keith Grzadziel: A fire was reported at a commercial building on the roof at 543 S. Arthur Ave in Arlington Heights. I was in the area and captured these photos, but I arrived after the fire had already been brought under control. The scene looked intense, and it's clear that the firefighters worked quickly to contain the situation.
