Smoke was billowing from two units on the third floor of an apartment building at 423 S. Lombard Ave., as of 8 a.m. Tuesday morning. Oak Park firefighters used ladders to reach the exterior of the units where they broke windows to vent the smoke. No injuries were immediately reported. Oak Park police worked to evacuate residents, largely older people, from all apartments.
A fire official said it was too soon to know the cause of the fire.
