A firefighter suffered minor injuries while battling a two-alarm fire in Reading early Wednesday morning.
The first firefighters were dispatched shortly before 3:30 a.m. to the 900 block of Perry Street, where they found flames shooting from the second and third floors of a vacant, three-story row home.
A deputy chief quickly struck a second alarm, calling for additional manpower from elsewhere in the city, as well as from neighboring Muhlenberg Township.
Firefighters worked about a half-hour to put out most of the fire, which was declared under control shortly before 5 a.m., 90 minutes after the initial dispatch.
The city's fire marshal is working to determine what sparked the blaze.
No one other than the one firefighter was injured.
