Firefighters from the Pittsburgh Bureau of Fire responded to a one-alarm fire inside the Allegheny Sandwich Shoppe at 822 Western Avenue on the North Side.
When firefighters arrived on scene they discovered a fire that appears to have originated in the electrical room and stayed mostly confined to that space.
There was a significant amount of smoke, but firefighters were able to extinguish the fire quickly, keeping it from spreading.
The business is closed on Sundays. There were no injuries to firefighters or anyone on scene.
The Fire Investigation Unit, made up of investigators from the Pittsburgh Bureau of Fire and detectives from the Pittsburgh Bureau of Police, is investigating the exact cause of the fire.
Tonight, the City-County Building is illuminated to recognize Poison Prevention Week and the 50th Anniversary of "Mr. Yuk" in partnership with Children's Hospital of Pittsburgh of UPMC.
For questions about the lighting at the City-County Building, please reach out to the Office of the Mayor.
