Significant harm to children gives rise to both child welfare and law enforcement concerns and section 47 enquiries may run concurrently with police investigations concerning possible associated crime(s). The police have a duty to carry out thorough and professional investigations into allegations of crime and the obtaining of clear strong evidence is in the best interests of a child, since it makes it less likely that a child victim will have to give evidence in criminal court. Enquiries may, therefore, give rise to information that is relevant to decisions that will be taken by both local authority children’s social care and the police. The findings from the assessment and/or police investigation should be used to inform plans about future support and help to the child and family. They may also contribute to legal proceedings, whether criminal, civil or both.
