The Cedar Rapids Fire Department and Hiawatha Fire Department both responded to the scene, where an official release says they found a light haze inside Riley’s Cafe. Using thermal imaging, firefighters reportedly checked the ceiling in an area already impacted by a fire Thursday afternoon. After discovering hot spots, the firefighter reportedly began removing ceiling tiles and identified burning insulation and falling embers. Firefighters reportedly discovered multiple instances of burning insulation above both Riley’s Cafe and the neighboring Broken Spoke, both of which had already been closed because of Thursday’s fire.
