Residents in Shetland are being urged to be on their guard after a series of telephone scams.
A number of islanders have become targets for fraudsters using different cons in recent weeks.
One case saw and individual lose a sum of money stretching into tens of thousands of pounds.
In the majority of cases including the most recent incidents in Shetland, the criminals phone individuals claiming to be a representative from their bank and advise them that their bank account has been compromised.
The victim is then encouraged to transfer their money into an account provided by the fraudster.
This type of fraud is commonly known as “vishing”.
Police are urging people to be aware of calls and contact of this nature, and in particular to ensure their elderly or vulnerable family, friends and neighbours are also aware of this type of scam and to be on their guard.
Constable Rachel Branney, Shetland preventions and interventions officer, said: “These are ruthless crimes which can have extremely sad outcomes for those targeted.
“Over recent weeks here in Shetland we have seen victims defrauded of thousands and sadly this week an incident involving tens of thousands of pounds. No price can be put on the devastating impact of losing life savings at the hands of these despicable fraudsters.”
She added: “Please always be on your guard if you are contacted on the telephone by anyone claiming to be from your bank, or indeed any other company such as an electricity supplier, and especially if the call involves transferring money, providing or confirming your bank details.”
“I cannot emphasise enough, if you have the slightest doubt, attend your bank in person. Do not provide your details over the telephone or the computer.”
