FRESNO, Calif. (FOX26) — The Fresno Fire Department responded to what it thought was an apartment fire around 6:30 p.m. near Blackstone and Sierra Avenues on Monday.

As fire crews arrived, they found a large column of thick black smoke visible for miles.

The 911 calls reported the fire was coming from an apartment complex located behind Clawson Motorsports on Blackstone Avenue.

Firefighters determined the fire had spread into nearby vegetation and was threatening a two-story apartment building, but then discovered the main source of the fire and smoke was actually burning in the back lot behind Clawson Motorsports.

They took a defensive position to protect the apartment building from the advancing flames while redirecting incoming resources to attack the main fire in the dealership lot.

The apartment building was successfully protected, and no injuries were reported.

Eleven UTVs in the dealership lot were damaged in the fire.

The cause remains under investigation.
