Lancashire Constabulary's going online to warn people about bogus emails which con their victims out of large sums of money.

The force has produced three podcasts offering advice on how to deal with the 'criminal cash back' scam, the 'advanced fee fraud' scam and the 'Spanish/Canadian lottery' scam.

Victims of the criminal cash back scam receive an email offering employment which involves cashing cheques through their own personal accounts.

They are told they can keep 10 per cent of the balance but are asked to forward the rest to another account.

The scam is made all the more real when the victims are sent contracts of employment on letter headed paper from legitimate companies.

However, after sending 90 per cent of the balance the victims find that the cheques are returned unpaid leaving them out of pocket.

In the advanced fee fraud scam people are asked to make a payment in advance for a 'business deal' or to provide their bank details so payment can be made into their account, which of course never happens.

And in the Spanish/Canadian lottery scam people are told they've won the lottery and are asked to make a payment to cover an admin fee. They are also asked for their bank details so payments can be made into their accounts.

The victims not only part with their money but give fraudsters access to their bank accounts.

DC Mark Turner, from Lancashire Constabulary's Economic Crime Unit, said: "The best way to deal with these emails is to delete them. If they sound too good to be true then the chances are they will be.

"Never ever send any money or provide your bank account details in reply to these emails."
