Government Office, Government/Military Riverside, CA – Arson fire at social services building contained by sprinkler system; No injuries reported August 18, 2017 viking210 A chair and other items in the Riverside County Department of Social Services building in Riverside’s Arlington neighborhood were set on fire Saturday night, authorities say. Nobody was hurt in the fire, which set off alarms at 7:37 p.m. at the 21,000-square-foot building in the 3900 block of Reynolds Road, behind the Lowe’s on Magnolia Avenue, according to a Riverside Fire Department news release. The statement did not say anyone had been arrested. Arriving firefighters found that the front door had been forced open and smoke was coming out, the news release said. When they went inside, they found “evidence of vandalism.” The fire set off the building’s automatic sprinkler system and it was contained to an “office area,” the news release said. That’s where firefighters found a chair and other items that had been ignited. Firefighters shut off the sprinkler system and removed “large amounts of water from the building,” the news release said. The Fire Department’s Arson Task Force is investigating.
