This book has been produced by the Metropolitan Police Fraud and Linked Crime Online (FALCON) team to make you aware of the latest and most prolific scams. This version has been designed specifically to protect small and medium enterprises (SMES), which account for 99% of all UK businesses and employ over 13 million people. The impact of fraud is often more dramatic in SMES which simply cannot afford the losses that may arise. Often, these losses can result in business failure. It is important to recognise that a fraud can come from anywhere; internal staff, customers, suppliers as well as unconnected third parties. Fraud can also seem inherently complicated and difficult to understand as criminals use a range of tools and techniques at their disposal.
