Eighteen students from two schools in Nairobi have been arrested for questioning over a plan to strike and torch facilities.
Police said 15 were from Aquinas boys’ and the rest from Huruma Girls’ high schools.
Police said security was beefed up at the institutions amid interrogation of suspects.
Incidents of school unrest have been on the rise and have left many learning facilities damaged and schools closed.
The Department of Criminal Investigations has also warned students behind the unrest that their actions will be recorded in certificates of conduct after they leave school.
