Kenyan police are investigating a case in which three pupils were tied to a tree as punishment for truancy.

They are questioning two senior teachers at Thiru Primary School in Laikipia County in central Kenya over the incident.

The incident sparked anger among Kenyans.

Local television station NTV says the learners are aged between seven and 11 years:

Moses Muroki, a government official in the county, told journalists that the incident happened on 20 August.

He said the pupils were being punished for "truancy and delinquency".

The county's head of children services, Ezekiel Mwanza, said they apologised to the children, saying it was “unfortunate that our children could be subjected to such inhumane treatment”.
