They have responsibilities for unaccompanied children, as well as those who arrive in the UK with their parents and about whose safety and welfare there are concerns.
If you feel your local Children's Services would benefit from advice on how to respond to child trafficking cases recommend they contact NSPCC CTAC or ECPAT.
