National guidance should be produced to inform the decision as to whether or not to notify the police. This guidance could usefully draw upon the criteria included in a local protocol being developed by Sheffield Social Services and brought to the attention of the Inquiry. The decision would therefore take account of: age or power imbalances; overt aggression; coercion or bribery; the misuse of substances as a disinhibitor; whether the child's own behaviour, because of the misuse of substances, places him/her at risk so that he/she is unable to make an informed choice about any activity; whether any attempts to secure secrecy have been made by the sexual partner, beyond what would be considered usual in a teenage relationship; whether the sexual partner is known by one of the agencies (which presupposes that checks will be made with the police); whether the child denies, minimises or accepts concerns; and whether the methods used are consistent with grooming.
