A 10-year-old boy died in an apartment fire that broke out in a third-floor unit at the NYCHA-run Pink Houses in East New York last night. The cause of the fire is still under investigation.

According to the NYPD, officers responded to eight-story 1257 Loring Avenue shortly after 9:40 p.m. on Thursday. Upon arrival, they determined that the fire had started inside apartment 3H. FDNY responders found a 10-year-old boy inside the apartment, unconscious and unresponsive. EMS also responded to the scene, and pronounced the boy dead upon arrival.

An FDNY spokesman confirmed that the fire did not spread to any other apartments, and was under control by 10:17 p.m. Three other victims sustained "minor injuries," but were not transported to the hospital.

The Post reports that the boy was asleep in his bedroom when the fire broke out. Three other siblings in the room were able to escape.

"The fire was quick and strong in the room,” one neighbor told the tabloid. "The father tried to get in to save him, but the smoke and flames stopped him.”

The cause of death has yet to be determined by the medical examiner, and an investigation into the cause of the fire is ongoing.
