Police in Kibra on Monday arrested a KCSE examination supervisor after she allegedly unknowingly opened the wrong examination papers.

Kibra Deputy Commissioner Gideon Ombogi said the supervisor attached at the Olympic Secondary School in Kibra unwrapped the English Paper 2 exam instead of paper 1 while issuing out the tests.

According to sources at the school, the teacher had distributed the papers to some of the candidates.

The papers were recalled from the students after two streams had received the said papers on their desks, Citizen Digital reports.

Commissioner Ombogi said the exam did not leak as the supervisor did not display the paper’s contents.

The female teacher was taken to Kilimani Police Station to shed more light on the circumstances under which the mishap happened.

The English Paper 1 test was scheduled to be the first exam while Paper 2 was set for mid-morning.

The Form Four national exams began on Monday across the country, with 699,745 candidates sitting for the Kenya Certificate of Secondary Education (KCSE) tests.
