A so-called courier scam involving people being persuaded to hand over their bank cards to criminals has lost victims more than £3m, since 2011.

New figures from the Metropolitan Police show that 2,967 people in London were targeted from January 2011 until September 2013.

"Courier fraud" involves criminals phoning victims pretending to be from an authority to extract pin details.

One basic feature of the fraud is that when you put down the phone, the scammer keeps the line open so that whoever you attempt to call it is actually still the fraudster you're speaking to. They'll play a dialling tone to make it appear that you're phoning the card company or the police but they'll impersonate whoever you think you're calling to confirm or report what's happened.

Therefore, if you can, make any report by mobile phone or try ringing a friend or relative first, to check that your line hasn't been hijacked by the fraudster.
