Kealakehe High will temporarily beef up security and decrease the amount of time students have for lunch and breaks after several large fights linked to rising “cultural” tensions at the Hawaii island school spurred the cancellation of classes today, Department of Education officials said.

Students will return to the campus Monday.

DOE officials and parents blamed the tensions on discord between two relatively small factions of students — and to changing community demographics.

On Thursday, eight students were arrested at the school following a melee that involved about 30 students. Those arrested Thursday — seven males and one female — were charged with disorderly conduct and released.
