A court has sentenced a 23-year-old volunteer primary school teacher in Kenya to 90 years imprisonment for sexually abusing his pupils. John Gichia Mugi was charged with sexually assaulting 10 boys when he was their boarding master at a primary school in 2015. 


The judge said the teacher had betrayed parents' trust and committed a horrendous act on the boys he was supposed to look after. 


The 90-year jail term may be one of the longest and jail term given to a sexual offender in Kenya.
