The roof of the dollar store collapsed in the early Friday morning fire near 75th and King Drive.
Two stores on Chicago's south side were badly damaged in an early Friday morning fire that left one firefighter with an injured hand.
Flames and heavy smoke were already shooting through the roof of the Dollar & Up store near the intersection of East 75th Street and South Martin Luther King Drive when crews responded about 12:15 a.m., Chicago Fire District Chief Tim Sampey told reporters at the scene.
Firefighters quickly upgraded the fire as flames spread to the adjacent Cricket Wireless store.
The roof of the dollar store collapsed in the fire, but the extent of damage to the cell phone store was unclear early Friday.
The fire was out by 1:35 a.m., according to Fire Media Affairs.
One firefighter suffered minor injuries to his hand and was taken in stable condition to the University of Chicago Medical Center, Sampey said.
The cause of the fire was under investigation.
