More than 100 firefighters responded to the fire.
"Because of the size and the length of the building we had to escalate the alarm for more manpower," Assistant Deputy Fire Commissioner Donald Walker said. The building sustained major damage, including the collapse of the roof.

There are no reports of any injuries. The cause of the fire is under investigation.
