The City of New York Fire Department responded to a reported fire at 927 Grand Street in Brooklyn, which involved a three-story mixed-occupancy building with associated exposures, shortly before ten o'clock on May 3.

Firefighters found a large fire on the first level, which swiftly spread through empty spaces and onto other buildings, according to officials. According to Paul Miller, Deputy Assistant Chief, the building's design made it possible for the fire to spread quickly through the cockloft and nearby exposure. Because of worries about structural stability, technicians moved from interior to outside operations after ensuring all inhabitants had safely fled.

Five tower ladders were working at the location during the peak of the four-alarm fire. Firefighters were evacuated from the location as a wall from the original fire building collapsed onto the street during suppression attempts, followed by a back wall collapsing into the structure.

Three firefighters were sent to a nearby hospital after suffering minor injuries. There were no reports of missing civilians. The cause is still being looked into.
