Teachers and administrators returning to work Monday reportedly discovered the damage.
Surveillance video shows four men inside the building on New Year's Day between 3:30 a.m. and 4 a.m.
Authorities say the suspects were able to get into the school by breaking out windows in the rear of the building.
School officials are offering a $1,000 reward to anyone who has information that can lead to the arrests of the suspects.
