Maranda High School has been closed indefinitely following Sunday night's fire that gutted down a dormitory.
The decision to close down the school was reached after a board meeting held on Monday.
The board arrived at the decision to give the school management time to reconstruct the 200-bed capacity dormitory that was destroyed by the fire.
Siaya county director of education Nelson Sifuna said six students have been arrested.
They were taken to Bondo police station for questioning.
The county director further noted that security guards will also be interrogated.
He called for calm among all stakeholders.
"The students will soon be recalled once proper mechanisms have been put in place," Sifuna said.
He said that the value of the damage to the building was yet to established and therefore the amount that each student will be expected to pay could not immediately be determined.
He urged principals in the county to remain vigilant to avoid such incidents in their schools.
