LA PUENTE — A fire scorched a tortilla-making factory Wednesday afternoon, authorities said.

The fire was first reported about 3:30 p.m. at Sope Ozzy’s, 818 N. Hacienda Blvd, Unit A, Los Angeles County Fire Department Capt. Art Lopez said.

The blaze was mainly contained to a large oven at the business, the captain said.

About 25 people were evacuated from the factory and other nearby businesses during the fire.

Firefighters extinguished the fire in about 20 minutes, Lopez said. It caused an estimated $70,000 worth of damage to the oven and other kitchen equipment, as well as about $5,000 worth of structural damage.

The cause appeared to be a malfunction in the oven, he added. No injuries were reported.
