Whenever the police detain a child or young person (aged 10 to 17), or interview them as a voluntary attender, they must inform an appropriate adult as soon as is practicable and ask them to attend.

Section 63B(10)(a) defines who may act as an appropriate adult. If a parent, guardian, representative of the organisation responsible for their care or a local authority social worker is unavailable any responsible person aged 18 or over may fulfil the role. The exception is police officers and police employees
