CHICAGO (AP) — Five people were hurt early in a carbon monoxide leak and fire in a Chicago apartment building, fire officials said.
Firefighters were called for high carbon monoxide readings about 4:30 a.m. at the North Side building.
Four people were taken to a hospital for treatment.
Crews found a faulty furnace and returned carbon monoxide levels to normal a short time later, officials said. Residents then were allowed to return to the building.
About 30 minutes later, a small fire was found in one of the units, officials said. The blaze was extinguished a short time after it was discovered.
One person was taken to a hospital with a minor burn, officials said.
