Trash cans deliberately set on fire at Roosevelt High School in Boyle Heights, LAFD says

BOYLE HEIGHTS, LOS ANGELES (KABC) -- An arson investigation is underway after more than a dozen trash cans were set on fire at Roosevelt High School in Boyle Heights early Wednesday morning, the Los Angeles Fire Department said.

The blaze erupted at the high school in the 400 block of S. Mathews Street around 4 a.m. and then spread to a janitorial building.

Responding firefighters found a pile of debris against the janitorial building as flames wrapped around the back wall and up the roof of the structure.

Fire officials observed multiple starts and say it appears someone tried to start the fire from the exterior.

It took firefighters about 15 minutes to knock down the flames, which caused mostly smoke and water damage. No injuries were reported.

Officials with the L.A. School Police Department say classes will not be affected Wednesday, and the school will resume its normal operations.

Police say they plan to turn to video surveillance footage for clues in the investigation.
