Islanders have lost more than £700,000 to online scams so far this year.
That’s up from £86,000 In 2017.
The number of people reporting that they have been targeted by internet fraudsters has more than doubled in the past 12 months.
Police say there have been 172 cases, compared to just 81 in 2017.
Not all of those have lost money, but 20 people have been conned out of a a combined £736,000.
In the same period last year, 15 people lost £86,347.
Jersey’s Fraud Prevention Forum says that in most cases criminals are tricking people into parting with their savings by pretending to be from a bank, the police or utility company.
Chairman, DCI Chris Beechey, says islanders can sometimes be too trusting, and we need to remember that people aren’t always who they say they are.
“Impersonation and deception scams are being commonplace. If you get a call, text, email or social media message asking you to disclose your personal or financial information, you should always double-check that the request is genuine.”
