Defining organised crime in terms of specific threats is a practical way of understanding and tackling it. While some organised criminals may specialise in a particular criminal trade, many are entrepreneurial and opportunistic by nature. Significant numbers of crime groups, especially the larger, more established ones, are involved in two or more profit-making criminal activities. The one threat on this list which is common to nearly all significant groups of organised criminals is money-laundering.
In addition to the information listed below, further analysis of the threats from serious and organised crime faced by the UK can be found in the pdf National Strategic Assessment of Serious and Organised Crime 2017 (1.97 MB).
