According to the LAFD, firefighters responded to City Hall – located at 200 N. Main Street in downtown L.A. – around 8 p.m.
Preliminary reports indicated that an object was apparently thrown into the building, causing the fire to start.
Fire crews arrived on scene and responded to an activated alarm on the second floor of the building. A sprinkler helped contain most of the fire, LAFD said.
“LAFD firefighters found evidence that the fire was started suspiciously,” a spokesperson for the LAFD confirmed to KTLA.
A fire department spokesperson told the LA Times that the fire started in the office of Chief Legislative Analyst Sharon Tso.
Tso later confirmed that there was a fire in her office, but also said that she could not comment further on the matter.
Arson investigators with the Los Angeles Fire Department are handling the ongoing investigation.
