From the running of boys' clubs and catching truants to supervising troublesome kids and giving them a 'clip round the ear', the role of the police has been a recurrent theme in the debate about juvenile delinquency. Set against the context of wider developments in youth justice in Britain, this book examines the origins, key features and outcomes of police work with young people, the realities of multi-agency decision-making, and the impact on young people and their families.
