Two Los Angeles firefighters are OK after falling through the second floor of a two-story office building that erupted in flames Friday morning.
The flames started outside but went into the building, believed to house medical offices.
The firefighters fell when there was a partial floor collapse, KTLA reported adding they were transported to be checked out.
“The arson investigation is here … undetermined at this time as to how this fire started,” LAFD Assistant Chief Steve Hissong said.
