Fourteen people have been charged over a £300,000 fraud scheme which mainly targeted the elderly.
Police have traced over 34 people across the UK affected by the scheme – with many losing their life savings.
In Central Scotland, where the local force led the inquiry, 14 people were targeted.
Detectives first became aware of the scam last summer and set up Operation Jenga, sharing the information with the Scottish Crime and Drug Enforcement agency, as well as forces across the country.
Leading the inquiry was Detective Frank McCann of Central Scotland’s serious organised crime unit. He said: “We set up an investigation which revealed it was complex and spanned the whole of the UK.
“Fourteen people in our force area had more than £300,000 taken from them – in some cases their life savings were taken. There were attempts to defraud 21 other people out of their money.”
He added that these crimes were linked to similar investigations taking place in other parts of the country.
Those targeted were typically contacted by phone by people pretending to be bank officials or police officers, claiming their bank accounts or cards have been compromised in some way. They were persuaded to give their bank details or to hand over their card to a courier.
Charges relate to being the courier to collect the bank card, allowing bank accounts to be used to transfer money and carrying out transactions using fraudulently obtained cards.
