‘Knarkrondellen’, which translates to ‘Drug Roundabout’, is a known hot spot for drug trading in Malmö and the police have implemented several measures to prevent the narcotic crimes. This paper sets out to investigate the impact that the police interventions, namely enhanced police foot patrols, improved street lighting and the installation of a surveillance camera, have on the crime rates and the fear of crime at the roundabout. In a multi-method approach, quantitative data from the police register and police surveys as well as qualitative observations and interviews with the residents are analyzed. The findings show that the police interventions did not reach the desired preventative effect in the given study period and indicate the occurrence of displacement. The citizens’ feeling of safety and perception of the problems did not change significantly as a result of the interventions. Overall, the surveys and interviews suggest that the police are on the right track; however, a longer follow-up period is needed in order to examine the long-term effects of the intervention measures. Additionally, an enhanced involvement of the community in the fight against drug crimes appears necessary.
