Knarkrondellen' , which translates to 'the drug roundabout' , is a known hot spot for drug trading in Malmö and the police have implemented several measures to fight the open drug market. 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, exert on the crime rates and the fear of crime at the roundabout. Quantitative data from the police register of reported crimes and police surveys are analyzed. The findings show that the police interventions did not reach the desired preventative effect on crime in the given study period and possibly indicate the occurrence of displacement. Nor did the citizens' feeling of safety and perception of the problems change significantly as a result of the interventions.
