Various sources have claimed an electric fault was the major cause of the frequent fires at the school.
On Wednesday, Kakamega North Sub-County police officer in charge of operations Samuel Koskei said the cause of the fire is yet to be known.
The school principal, Mr Bernard Lukuya, declined to speak on the matter.
A 500 capacity dormitory at Musingu High School in Kakamega North sub-county was destroyed in a fire that broke out on Wednesday morning.
The first floor of ''Oparanya hostel'' that was funded by the County Government of Kakamega and named after Governor Wycliffe Oparanya, an alumnus of the school, is said to have caught fire as welders were repairing broken windows.
