Youth crime is a topic that has taken place in the media and has engaged politicians as well as researchers. This is a problematic phenomenon that can contribute to various social problems in the future by affecting youth and society. Since youth crime can lead to various social problems, it is important to examine and highlight the problem, how it can lead to various social problems, but also how society can prevent these social problems. The purpose of this study is to create a deeper understanding of how social workers imagine and frame crime among young people and how they work preventively in their practical work. Based on the collected empirical evidence and previous research, we can draw conclusions that juvenile delinquency is very complex and there is no clear explanation about that subject. We have collected empirical evidence through eight semi-structured interviews where the respondents were selected with conscious selection.The results show that the social worker's individual beliefs about risk identification depend on academic discipline, experiences, collaboration and further education. However, the respondents specify that family and dysfunctional schooling is central. The results show that the material we have collected from the respondents is consistent with previous research and theories about juvenile delinquency.
