Authorities said three units worked to extinguish a fire at a commercial building in Dallas Thursday morning.
Dallas Fire-Rescue officials said crews arrived at the vacant one-story building in the 2900 block of Walnut Hill Lane at about 1:45 a.m. flames shooting through the roof.
Firefighters worked to control the flames and called for backup.
"The third alarm response was strictly for manpower," Dallas Fire-Rescue spokesman Jason Evans said.
No injuries were reported.
The cause of the fire is currently under investigation.
