Two men from Belfast and Omagh have been conned out of a total of almost £40,000 in separate telephone scams.
It has prompted police to issue a warning following the reports of fraud.
One of the victims from Belfast received a voicemail last month asking him to get in touch with his internet provider.
He called back the next day and was told there were issues with his broadband and he needed to download a program so the matter could be resolved.
However police say the man downloaded a programme which gave the fraudster access to his computer.
“The man was also told he would be compensated for the problem and was asked to log onto his online banking, which he did. As the scammer had access to the man’s computer, he was then able to access his online banking and take £19,800,” Chief Superintendent Simon Walls said.
He said people are continuing to lose very significant amounts of money in online and telephone scams.
“This has been an awful ordeal for this man who believed he was communicating with a legitimate representative from his internet provider, but who in turn was swindled out of thousands of pounds,” he added.
In the second report, the victim from the Omagh area had received a call from a person claiming to be from telecoms provider who told him he had issues with his internet and, to resolve the problem, he would have to install an app on his mobile device, which the man did.
Again, this enabled the scammer to take control of the man’s phone and gain access to his bank account, taking just over £19,700.
“While this may have sounded like a completely legitimate call, it illustrates how convincing scammers can be,” added Chief Superintendent Simon Walls.
Police are asking people to be wary of calls.
“I want to take this opportunity to appeal to members of the public to always err on the side of caution with any text, call, email or letter asking for payment or personal details in order to release money, refund fees, pay lottery wins or supply a holiday, giveaway or service. Tricksters know all the scams and will often communicate with victims in a convincing manner.
“Our advice is that if you are at all suspicious about a call you receive, hang up and phone the organisation the person is purporting to represent to check their authenticity. Ideally, make the call from another telephone so you can be sure the original caller has not remained on the line. Never be pressured into a transaction over the phone,” added Chief Superintendent Simon Walls.
He said guarding personal and banking details is essential. Never ever disclose them to any unauthorised person or allow anyone access to them via your computer.
If you have received a call of this kind or if you’re concerned by the intent of unsolicited calls, emails or letters then please report it to Action Fraud via their website www.actionfraud.police.uk or by phoning 0300 123 2040, or call police on the non-emergency number 101.
