Shortly before 10:00 PM, Beaumont Fire Rescue units responded to a reported structure fire at 1905 Calder Ave. When firefighters arrived they found a rear corner of the building engulfed with flames. Firefighters were able to make a quick attack to extinguish the fire and confine the fire damage to the exterior of the building with only minor damage to the interior. The cause of the fire appears to be deliberate. The building is the law office of Chris Portner. There were no injuries and the investigation is continuing.
