ALLENTOWN, Pa. (WTXF) - Firefighters in Allentown worked through the night as they battled a fire at a vacant warehouse.
Flames broke out at a vacant warehouse on the 400 block of North Franklin Street around 6:30 p.m. Sunday.
Almost 12 hours later, fire crews were continuing to put water on the four-story building Monday morning.
Officials say the fire broke out on the lower floors, but quickly spread to the upper floors, and eventually through the roof. The fire's climb has caused concerns about a potential collapse.
One firefighter suffered burns to his hands and arm, and was released from a medical center. No other injuries have been reported.
The cause of the fire remains under investigation.
Allentown fire officials say demolition crews from Kutztown are on the way to the scene. Officials say it will be demolished by Wednesday at the latest.
