If you've been a victim of fraud, and there isn't immediate danger, contact Action Fraud on 0300 123 2040
Action Fraud is the UK's first national fraud reporting centre, which 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.
Action Fraud provides a single place for victims of fraud to report to, or get advice on protecting themselves. For more advice or to report a fraud, visit www.actionfraud.police.uk or call 0300 123 2040.
Their phone lines are open:
Mon to Fri - 8am to 9pm
Sat to Sun - 9am to 5pm
Closed bank holidays
You can report a fraud via the Action Fraud website 24 hours a day, seven days a week.
You can also follow Action Fraud on Twitter on @actionfrauduk, or visit their Facebook page via www.facebook.com/actionfraud.
If debit or credit cards, online banking or cheques are involved in the fraud your first step should be to contact your bank or credit card company.
