A fraud squad is a police department which investigates fraud and other economic crimes, the largest of which in the United Kingdom is run by the City of London Police.

This unit is responsible for policing London's and the UK's main financial hub, as part of the City of London Police Economic Crime Department (ECD) It investigates what could be described as traditional fraud offences such as banking frauds; insurance frauds; investment frauds; insider dealing frauds; advance fee frauds and Internet frauds, amongst others. Each team is headed by a Detective Inspector who take it in turn on a weekly basis to act as the "Duty Squad" and they form the immediate response to any calls received concerning new fraud cases.

The Fraud Squad is a specialist area, usually a part of the Specialist Investigation Department, where officers are normally transferred from general detective duties with the Criminal Investigations Department (CID). Some officers will be nominated to work on specific cases for the Serious Fraud Office (SFO), they will also provide assistance and advice on policing matters to the SFO and Financial Services Authority.

The City of London Police has recruited accountancy specialists directly into its Special Constabulary, and these officers primary duties are assisting in complex fraud investigations.^[1]

The Ministry of Defence Police (MDP) also maintains a sizeable Fraud squad within its CID. This squad investigates serious fraud and corruption offences against the Ministry of Defence.
