Bill fraud: Gwynedd utilities scam warning by North Wales Police
Householders in Gwynedd are being warned to be on the lookout for a fraud where victims are offered a reduction in utility bills.
North Wales Police say one woman in her 60s was recently conned out of £650.
Officers say criminals are contacting victims at random by their home phones, claiming they are from a national utilities company.
They offer a reduction in bills if cash is paid into a Paypoint account.
The con involves householders being provided with a Paypoint account number and a telephone number for the person to call back once the payment has been made.
A false number is also provided for the company's "UK office".
PC Delyth Bryan, based in Caernarfon, said anyone with any doubt should put the phone down.
"If you have any doubt simply cut them off as soon as they make contact and inform your telephone provider.
"Any responsible organisations will make contact with their clients in writing with a nationally recognised number to call if there are any concerns," she added.
Police also advise the public to never provide bank details when prompted by an unknown caller.
"If you do fall foul to a scam and lose money inform your bank immediately that your account has been compromised and call North Wales Police on 101 for any advice," said a spokesman.
