TAMPA, Fla. — Fire investigators are trying to determine what sparked a fire that destroyed a South Tampa restaurant early Monday.

Tampa Fire Rescue responded to a structure fire at the Fresh Kitchen, located in the 1300 block of S. Howard Ave., at 4:45 a.m.

Officials said firefighters found heavy smoke pouring out of the two-story structure.

After initially going into the building, crews were pulled out of the building out of caution.

Due to the intensity of the fire, a second alarm was called for additional resources. There were no injuries to firefighters or civilians reported at the scene.

A primary and secondary search was completed with no occupants in the building.

Due to the location of the building, northbound and southbound lanes of S. Howard Avenue were shut down for several hours for the safety of first responders.

Tampa Fire Rescue arrived earlier Monday and are continuing to investigate the fire.
