Kenyan officials say the country's examination board has been dissolved and its members will be arrested following reports of widespread cheating in the university entrance exams for high school students.

Internal Security Minister Joseph Nkaissery ordered Thursday the arrest of the nine members of the Kenya National Examination Council.

Education Cabinet Secretary Fred Matiang'i added that evidence showed the officials were involved in the cheating.

President Uhuru Kenyatta has since appointed former University of Nairobi Vice Chancellor George Magoha to be the new chairman of the examinations board to clean up its image.

Kenyatta took office in April 2013 and has repeatedly promised to eradicate corruption. Despite firing six ministers, critics say Kenyatta is not doing enough.
