Life on the Edge: Korogocho's biker boys

Boniface is one of the founders of the motorcycle boys in the Nairobi slum of Korogocho.

They are a team of young men who used to steal from their neighbours, but now drive them around Korogocho on their motorbikes for a fee.

BBC News follows Bonnie and his friends as they try to prove that they can go straight and make their home a better place.
