Action Fraud, the UK's national fraud reporting centre, takes crime reports from victims of cheque, credit or debit card and internet fraud and provides a crime reference number.
This information is then fed to the police's National Fraud Intelligence Bureau to gain a more complete national picture of fraud. Action Fraud also provides a wide range of information about how to protect yourself from becoming a victim.
For more advice or to report a fraud, visit the Action Fraud website or call 0300 123 2040.
You should always contact your bank or credit card provider directly if you suspect fraud has been committed using your account, notice unusual activity on your account or lose your credit or debit card.
