Twelve people have been arrested after a KCPE candidate was found with a marked answer sheet in the exam room in Nyamira.
Anxiety gripped St Andrews Kaggwa Boys Boarding Primary School in Borabu Sub-County when Directorate of Criminal Investigations detectives pounced on the suspects on Thursday evening.
The officers were accompanied by officials from the Kenya National Examination Council Monitoring Unit.
Nyamira County Police Commander Titus Karuri and County Education Director Didacus Odhiambo confirmed the arrests on Friday.
Mr Odhiambo said the suspects were seized after a candidate was caught in the exam room with answers believed to be for the English Language paper.
“Knec officials will verify whether the materials smuggled to the exam room were actual answers for the English paper that was done,” Mr Odhiambo told Nation.co.ke by phone.
He said the Knec officials and DCI officers were interrogating the suspects to establish whether the exam was leaked at the school and the origin of the smuggled material.
The 12 spent Thursday night at Keroka Police Station.
They included the school headteacher Joseph Nyachieo, a KCPE supervisor, nine invigilators and the candidate.
Mr Karuri said police had not charged the suspects as investigations were still under way.
“It is too early to say exactly what each of the suspects will be charged with as investigations over the matter have just commenced,” he said.
“I will give finer details later as those investigating the matter make progress. But I can confirm the arrests,” Mr Karuri said.
St Andrews Kaggwa Boys is one of the primary schools in Nyamira County that have topped in KCPE exam performance for many years.
