Turkana County Commissioner Seif Matata told Kenya's Daily Nation newspaper that the suspect "was heard telling fellow students that he is going to burn the school or he will come back and avenge because of the suspension".
The irate crowd forced its way inside Kakuma Police Station and stoned to death a South Sudanese student who shot dead five students at a school in the area.
