At least nine people were hospitalized in a western suburb following a carbon monoxide leak, officials said.
The leak was reported just before 6 a.m. at a home in the 600 block of Rose Drive in Melrose Park.
The Village of Melrose Park said nine people, including children and adults, were taken to area hospitals from the scene. Earlier reports from the Northlake Fire Department indicated seven people were transported.
Gottlieb Memorial Hospital said three patients were taken to the hospital, but their conditions were not immediately known.
Other patients were taken to Loyola University Medical Center and West Lake Community Hospital.
Their injuries appeared to be non-life threatening, officials said.
Officials said a car that had been left running in an attached garage is believed to have been the cause of the fumes.
"We have not yet been able to interview any of the victims," Melrose Park Police Chief Sam Pitassi said in a statement. "But we have nothing to indicate at this time that there was foul play involved."
Local
Carbon monoxide poisoning is known as a silent killer: an odorless, colorless gas that can be generated by any appliance that burns fossil fuel, including any appliance in your house that burns coal, wood, charcoal, gasoline, or propane, according to the U.S. Consumer Product Safety Commission.
Symptoms of carbon monoxide exposure include headache, fatigue, shortness of breath, nausea, and dizziness.
At sustained CO concentrations above 150 to 200 parts per million, disorientation, unconsciousness, and death are possible.
