Five people, including an infant, were injured in a fast-moving fire in Brooklyn Thursday.
Flames broke out at around 12:20 p.m. on the third floor of a brownstone on President Street in Park Slope.
An adult and the infant were found in cardiac arrest. Both were transferred to Methodist Hospital.
Three other victims were also taken to the hospital with serious but non-life-threatening injuries.
Investigators have yet to determine a cause for the fire.
