Despite investigators finding out that the gun had no bullets, the school administration and students were thrown into panic, prompting the questioning of more students over the gun discovery.
The principal of the school, Mr Dickens Bula, said they received the hint about the gun from students who claimed that one student had been threatening to shoot them with the gun.
THREATS TO SHOOT
"We received complaints from students who said one of them was threatening to shoot whoever failed to meet his demands," said Mr Bula.
It is said the student was using the gun to extort money and food stuffs from fellow students.
The student is waiting to be charged with illegal possession of an unlicensed firearm at the Homa Bay Law Courts.
The discovery of the gun from the student has raised concerns on the safety of students in schools across the country.
The Homa Bay Police boss said they are also investigating how the student managed to get into the school with the firearm despite checks at the gate when schools open.
He cautioned parents with firearms at home to be careful on how they keep them.
"All weapons at home should be kept under safe custody to minimize injuries especially on children," he said.
