Action Fraud, the UK's national fraud reporting centre, takes crime reports from victims of 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.
Contact eBay/PayPal directly if you feel you have been a victim of fraud as a consequence of purchasing via their services.
Contact your bank or credit card provider directly if you expect fraud has been committed using your account.
