Los Angeles authorities say nobody was hurt when fire broke out on the campus of a Boyle Heights school, and the blaze is being investigated as possible arson.
Fire Department officials say flames were reported shortly before 4 a.m. Wednesday at Roosevelt Senior-Magnet High School.
The fire was contained to a one-story bungalow being used as a temporary classroom. It was knocked down in about 20 minutes.
The department says the flames began inside several trash cans placed around that building and a nearby second bungalow.
"The damage was limited to exterior, mainly just smoke on the interior," Margaret Stewart at the Los Angeles Fire Department told KPCC.
Arson investigators are reviewing surveillance footage.
School officials say classes will go on as scheduled Wednesday.
