A child trafficker has been jailed for four and a half years in Britain.
Police now hope that 35-year-old Kingsley Ojo can shed some light into the death of an unknown five-year-old whose torso was found in the River Thames in London in September 2001.
Ojo is thought to have been part of a network which brought hundreds of young people into Britain to work in the sex trade, as domestic slaves or for benefit fraud.
