A two-alarm fire raged at a vacant building in Allentown Thursday evening.
The flames were knocked down, but not before a firefighter was hurt, said Capt. John Christopher, Allentown Fire Dept.
Firefighters worked on hotspots following flames at 600 S. 10th St., across the street from Lehigh Valley Grand Prix.
It started around 6:30 p.m., and a second alarm was struck around 6:40, officials said. It was knocked down before 7 p.m. The second alarm was struck due to the sheer size of the building where the fire broke out.
Firefighters initially struggled to get water flowing from a nearby hydrant due to damage to the hydrant but another hydrant was opened quickly and eventually the initial one was able to be used as well.
