The noble Lord asks the right question. The child’s safety remains paramount. Enhanced risk assessments are required before the CHIS is tasked and are reviewed and updated throughout the duration of an authorisation. They are also updated after an authorisation is cancelled where contact with the CHIS is maintained. In the case of children aged 16 to 17, the law recognises that these assessments must be done on a case-by-case basis. Therefore, the presence of a responsible adult may or may not be required at that stage.
