Some PECO wires caught fire underground early this morning, giving Queen Village residents a scare.
NBC10 was first on the scene on the 700 block of East Passyunk Avenue.
Fire crews put out the fire, but a few hours later a carbon monoxide detector went off in a nearby home and that person called police.
When crews arrived back on the scene, they found high levels of carbon monoxide in homes and businesses in the area. Some evacuations were made as precaution.
The power was shut off while PECO checked the levels with a handheld meter.
No one was injured.
