About 130 Los Angeles firefighters battled a large fire at a fabric plant in Boyle Heights on Saturday night. Authorities were called to the 1600 block of Soto Street around 6:43 p.m., where they found French Fabrics, a 300-foot by 400-foot commercial building, engulfed in flames, the department said. The department initially reported the location to be in the 1500 block of South Rio Vista Avenue but later updated the address. The fire was burning through the roof and firefighters were forced to conduct a defensive operation due to high voltage power lines nearby. "This is a fabric, textile type of business and they have vast amounts of fire load inside of it," said David Ortiz with the department. "There was a lot of storage of those materials which meant that the amount of fire that was emitting from this building was too hot for firefighters to stay inside." The fire was declared a knockdown around 8:58 p.m.
