CHICAGO (CBS) — A Sonic Drive-In restaurant in northwest suburban Palatine was closed Tuesday afternoon for cleanup and repairs after a fire.

Crews were called at 3:55 p.m. when a fire alarm was activated at the restaurant, 1151 E. Dundee Road in Palatine, according to a statement from the Palatine Fire Department. Firefighters arrived to find welders working on the exterior of the building and smoke inside.

The fire was eventually located inside an exterior wall and extending up toward the roof, the fire department said. Crews had to open the interior walls and ceiling and breach the building’s exterior walls to expose and extinguish the fire, which was under control by 4:18 p.m.

No injuries were reported and the damage was contained to one corner of the restaurant, fire officials said. The restaurant will remain closed until repairs and cleanup are completed.
