A carbon monoxide leak at a Skokie apartment complex has sent dozens of people to the hospital.
The Skokie Fire Department got a call at about 3 a.m. Thursday of a sick person at an apartment building located at 8030 South Keating.
When paramedics got to the scene, they quickly realized there was a high level of carbon monoxide coming from the building and began to evacuate residents.
12 people, including children, were taken to the hospital with non-life threatening injuries.
No word yet if there were any working carbon monoxide detectors in the building.
The fire captain tells WGN it appears a faulty furnace is to blame for this leak.
Nicor gas was on the scene checking all the gas appliances in the five apartments, and they narrowed it down to one of the furnaces being the cause of the leak.
