No contact allowed despite no risk assessment result

[Shaftesbury]

Child in care while a specialist assessment was carried out on her father who has convictions for a child sex offence (now spent). Father has no restrictions at all and the assessment came back saying he poses no risk to the child. However, children's services say he is not allowed any contact as despite what the assessment says they still feel he is a risk to the child.

Would love some advice please!
