A center manager at Menara Academy in Muhoroni was arrested and held at Chemelil police station after photographs of Wednesday's Kenya Certificate of Secondary Education (KCSE) Chemistry paper were found on his mobile phone.

Education officials made the discovery while making routine rounds to monitor the ongoing national exams.

The suspect, Evans Ochieng Owili, is being held at Chemelil police station.

However, Education CS Julius Migos maintained that barring mobile phones from exam rooms was bearing fruit.

"In Nairobi, there were students who were found with phones, but they were found before they entered the exam room, so there was no compromise. Even the officers who are transporting the papers are allocated in the morning so that they do not become familiar with the team where they are going," Migos said.

The CS also urged the courts to expedite cases involving exam teaching. Eight teachers who were arrested for photocopying the Chemistry paper of a candidate who was unwell in Homa Bay were presented in court and released on Ksh.2 million bond each.

"They will never be able to teach in this country again," the CS said on the case.
