The police arrested the candidates and the invigilator at two different examination centres.
25 candidates were arrested at Somali Bantu Secondary School and 38 at Greenlight Secondary School.
At least 63 candidates who sat for the Kenya Certificate of Secondary Education and an invigilator spent the night in police custody on Tuesday after being arrested on charges of malpractice in the KCSE exam.
Police arrested the candidates and supervisor at two different test centers within the Kakuma refugee camp in Turkana West Sub County.
Turkana County Police Commander Samuel Nadani confirmed the arrest.
Nadani said 25 candidates were arrested at Somali Bantu Secondary School and 38 at Greenlight Secondary School.
3 Kenyans are not students but refugees.
He said the supervisor, identified as Edward Ekodor Lochole, was arrested and several phones of candidates at Greenlight Secondary School were confiscated.
“The preferred charges against the candidates and the supervisor were in addition to examination misconduct and dereliction of duty on the part of the supervisor,” Nadani said.
He said the candidates were released on a free bond so that they appear for the paper on Wednesday morning, while the invigilator was released on cash bail.
“The County Safety Team Committee and county officials from the Ministry of Education are already at the school to conduct a thorough investigation into the matter,” he said.
Nadani said the students will continue to take the exams as they await the education ministry’s recommendations.
Education CS George Magoha has condemned the use of phones by candidates in cheating during exams.
Magoha spoke at the Westland DCC’s office on Tuesday when he oversaw the distribution of exam papers.
“In terms of making sure all kids have equal opportunities, we’re more concerned about cellphones … in Kakuma we get phones equal to the number of students taking exams,” he said.
