Firefighters were called to a high school Friday morning before class started.
A fire was burning at Monterey Trail High School around 6 a.m. Elk Grove firefighters say it appears someone broke in to the band room, and a drum set was set on fire.
There is a lot of smoke damage to that room and some instruments, and large fans are being used to clear out the room.
Investigators are now trying to figure out how someone got into the performance room.
Classes will go on as normal Friday, music students will use a different room.
