Maui police suspect arson as the cause of a fire that resulted in $1.2 million in damage to Kahului Elementary School.

Police said the two-alarm fire started about 9:30 p.m. Friday and was burning in separate areas of the campus. A building in the middle of the campus was partially on fire and a portable classroom closer to the Maui High School parking lot was engulfed in flames, police said.

Seven fire companies responded and brought the fire under control at 11 p.m. The fire was extinguished at 12:50 a.m. today.

Damage to the structure was estimated at $900,000 and damage to the contents was estimated at $300,000, police said. No one was hurt.

The state Department of Education said the school will be closed for students on Monday so officials can assess the damage. The staff is to report to school.

The police investigation is continuing.
