VIDEO: An investigation is underway after a commercial building in Panorama City caught fire early Friday morning. The fire was reported shortly after midnight as flames engulfed the single-story building in the 14600 block of West Titus Street. The building appeared to house a packing company business. Materials used for the business were creating difficult firefighting conditions. The owners said no employees were inside the building at the time of the fire. Crews stopped the fire’s progress as of 2:20 a.m., according to a Los Angeles Fire Department update. Several dozen firefighters were still fighting the blaze as of 5 a.m. Aerial video from Sky 5 showed several pockets of fire still burning in side the structure. Flames were contained to the single structure, which is surrounded by apartment buildings and a nearby school. No injuries have been reported.
