It took 20 firefighters 45 minutes to put out flames that spread to a vacant commercial building from a transformer fire in Historic South-Central Los Angeles Saturday evening.
The fire was reported at 9:16 p.m. in the 3700 block of South Main Street, said LAFD spokesman Nicholas Prange.
The flames appeared to be on the roof when firefighters arrived but it turned out to be an upper wall and it sustained only minor damage, Prange said.
No injuries were reported, he said.
