Los Angeles County Fire Department officials said the two-story strip mall is located in the 4700 block of East Whittier Boulevard near Arizona Avenue.

It’s unclear what was inside the building that caught fire.

The fire was reported around 8:20 p.m. More than two dozen fire trucks were in the area battling the three-alarm fire, which crews eventually got under control just before 10 p.m. and announced a knockdown shortly after 10:30 p.m.

There’s no word yet as to what caused the fire, and officials have not reported any injuries.
