A dormitory has been burnt at St Peter's Nyamesocho Secondary School dormitory in Kisii County.
The incident occurred as parents in Kisii County raised concern over the increasing cases of fires in schools in the region.
The parents said they will not be forced to pay the costs of rebuilding the burnt dormitories while the arsonists go scot-free.
The parents, majority of them from St Peter's Nyamesocho Secondary School that was involved in the Wednesday night fire incident, said their children had nothing to do with the fires.
Nyamesocho becomes the seventh secondary in Kisii to experience an arson incident in the past two weeks, with parents beginning to raise queries on the security of their children.
No student was injured in the 8pm inferno, whose cause is yet to be established.
Property worth over Sh150 million has been lost in 10 schools in the past one month, for which parents are expected to pay.
Fire incidents in schools in the region have increased in the recent past, with parents now calling on the Government to establish their causes.
"The way such arson attacks are executed clearly absolves our sons and daughters from. Let the Government take time and investigate these cases. Most of the students are innocent," said Elizabeth Kemunto, a parent at Nyamesocho Secondary.
Ms Kemunto raised concern over failure to arrest the culprits. "We need to know what action has been taken on the previous culprits. We will no longer carry this burden," she said, noting that those who carry out arson attacks are known and yet no action was being taken against them.
The parents called on the Directorate of Criminal Investigations and the National Intelligence Service to investigate the incidents, and vowed not to pay the fines imposed.
"Why should we carry the burden of two or three people? Who are these people that the Government has failed to arrest?" asked Joseph Omariba, a parent.
"There is a tendency in this region of individuals resorting to primitive ways of settling scores. We should all understand that we have spent millions in putting up these schools," said Kisii County Secondary Schools Heads Association chairman Jairus Onchoke.
Education Cabinet Secretary Fred Matiang'i has warned that the Government will not use its funds to support what he termed as thuggery.
"There is no grievance that can justify the destruction of school infrastructure. We must be ready to sit down and solve any emerging issues," said Dr Matiang'i.
