Troubled British students travel to Tanzania

Ten British students with behavioural problems have embarked on a life-changing expedition to Tanzania.

Filmed by a BBC documentary team, the teenagers spent eight days trekking more than a hundred miles through the African bush.

The pupils were selected from 200 special schools in England and Wales to take on the challenging trip.

Trystan Williams, head teacher at Springfields Academy, and Matt Crosby, one of the pupils who went on the expedition, described their experience of meeting the nomadic Maasai tribes.
