On the subject of injunctions, I do not think that one is necessary here. The identity of the "victim" is protected under s37, s39 and s40 of the Children and Young Persons Act 1933. Any publication of names, addresses or schools such that victim may be identified become a quasi contempt of court. The same cover applies for committal proceedings under s8 of The Magistrates Court Act 1980 and s5 of The Sexual Offences (Amendment) Act 1992 which prevents publication of the victim's name in rape or other sexual offences. Since she was 14/15 at the time when sexual activities commenced then a charge of rape could be bought - even if she consented - since a child is deemed not to have the capacity to consent under the age of sixteen. So there are lots of reasons why her name cannot be disclosed.
If I recall the case correctly, the girl was initially named because it was a missing persons enquiry and nobody had had any charges bought against them. Even when the defendant was arrested in France and then extradited she could be named but as soon as he arrived back here and was charged then the entire case becomes sub judice and her identity (even though anybody who had read the papers would know it) becomes covered by the above act.
