The proliferation and capability of organised crime groups (OCGs), threaten to overwhelm the finite resources of police agencies. Although proactive ‘intelligence led’ approaches are more adept in identifying the most problematic offenders, responses predominantly rely on enforcement tactics, often delivering limited outcomes at significant cost. This paper outlines a case study involving a northern English police force, working alongside community safety partners and the public, in a bid to reduce the offending opportunities of an OCG. The multi-agency disruption tactics were categorised using the five themes highlighted by Cornish and Clarke (Criminology 25:933–949, 1986) in their Rational Choice Theory framework. The impact of the operation was evaluated by comparing criminal conviction data and police intelligence immediately prior to the police operation with similar data 2 years later. This was supplemented by semi-structured interviews with police officers (including patrol, detective, middle and senior ranking officers), partner agencies and the community. The operation was effective in reducing the threat posed by the OCG and was popular with those involved in its implementation. As it was delivered with no increased resources it provides a viable and cost effective method of reducing the threat of OCGs although further research is required to test its impact in different police agencies and against different OCGs.
