Fort Wayne Firefighters are trying to figure out what sparked a two-alarm fire at a Stellhorn Road office building.
Around 4:40 a.m., fire crews were called to an empty building fire at 340 Stellhorn Road.
The first crews on scene found heavy fire and flames through the roof of an empty business.
Crews were able to quickly put a stop to the fire, saving two additional adjoining offices.
A second alarm was then called to help the crews already on scene.
No one was hurt in the fire.
Fire investigators are asking anyone with information on how this fire started to call 260-427-1317.
