The Serious Organized Crime Agency (SOCA) tackles serious organized crime that affects the UK and its citizens. This includes Class A drugs, people smuggling and human trafficking, major gun crime, fraud, computer crime and money laundering.
Key Facts
SOCA's UK Financial Intelligence Unit (UKFIU) has national responsibility for receiving, analysing and disseminating financial intelligence submitted through the Suspicious Activity Reports (SARs) Regime. SARs provide pieces of information which alert law enforcement that certain client/customer activity, for example, the cash purchase of a high-value asset or a series of large out-of-character deposits - is in some way suspicious and might indicate money laundering or terrorist financing.
