Murfreesboro Fire & Rescue Department's Engines 1 and 4, Ladders 1 and 8, and Rescues 7 and 8 responded to a fire at 526 N Walnut Street (Legal Aid Society of Middle Tennessee and the Cumberlands) just after 11:00 Sunday night.
A Murfreesboro Police officer patroling the area saw flames at the back of the office building and notified Dispatch.
Crews arrived on scene to find a fire located at the exterior of the back door to the office.
The fire was knocked down quickly according to Shift Commander Tim Swann. "We had the fire out within three to five minutes," said Swann.
The Fire Marshals' Office was called to the scene to investigate.
"At this time, the fire appears to be suspicious in nature," said Assistant Fire Marshal Tracy Summar. "We know it started outside on the rear porch. I am following up with some contacts and taking samples to be sent off to the lab to determine if any ignitable liquids were present."
