The purpose of our study is to see how the interaction between the social services and police work when a child under 15 years is suspected of crimes. What happens to the child from an agency perspective? How is the experience for the child and how do they get their voices heard? How is the professional perspective for a child when a child is suspected of a crime? What do the various authorities for short-term and long-term measures for the child? We have chosen to do a qualitative study using semi-structured interviews. The study includes six interviews with two police officers, three field secretaries and a social worker in two different municipalities. A medium sized municipality, and a larger community. The people we interviewed think differently about collaboration. The municipality have different workforms. In the smaller municipality works a social worker at the police station once or twice a week. While in the larger municipality the police and social worker work separately but together nonetheless. The result shows that they are not completely satisfied with the interaction that is today, but it takes a lot of time to build it up and it can always be better. Furthermore, the study shows that the lack of time and resource issues control much of social service work. For the analyzes we have used a theory of interaction. The result shows that the professionals are using the children’s perspective a lot when they are working with children who are suspected of crime.
