McDonald's in Riverside is evacuated

A McDonald's at 4856 Airway Road was evacuated Friday night after a haze filled the restaurant.

Firefighters  could not locate the source of the problem and turned the situation over to the restaurant's maintenance staff, Riverside fire Lt. Chris Tesarz said.

Fire crews were dispatched to the address at 8:53 p.m. on a report of a structure fire. Tesarz said there was no smoke or fire, and firefighters initially thought there was an electrical problem or possibly a problem with the heaters, but could not locate the source of the problem.

There were no injuries or damage to the building, he said.
