BROOKLYN - At least six people, including four children, were sent to the hospital this morning after high levels of carbon monoxide were detected in a Canarsie apartment.

Firefighters responded to the scene on Rockaway Parkway at around 10 a.m. They say the level of carbon monoxide in the apartment could have been lethal, but all the victims are expected to recover.

The fire chief says a woman was found semi-unconscious in the bedroom and had to be dragged out of the apartment.

The building was not evacuated. The cause of the carbon monoxide leak is being investigated.
