PCSO Joanna Drake, at Louth Police Station, said: “There has been a recent telephone scam where the victim has been called by a person stating they are from Talk Talk and there is a problem with either the victim’s computer or broadband.”
“The victim is told they must purchase a number of iTunes vouchers amounting to at least £800 to enable the computer or broadband to be fixed.
“The victim is then directed to a specific shop or supermarket to purchase the vouchers.
“Once purchased, the victim is contacted again and reads out the code on the voucher to the scammer.
“Once the scammers have the code the iTunes vouchers are rendered useless and the victim has lost their money.”
Similar scams have involved the caller claiming to be from companies other than Talk Talk, such as utility companies and debt collection companies.
PCSO Drake added: “If you are contacted by anyone stating they are from Talk Talk and ask you to purchase any iTunes vouchers, please hang up the phone.
“This is a scam. Please do not give out any personal details including bank account numbers or bank card PIN numbers.”
Contact Lincolnshire Police on 101 if you believe you have fallen victim to a scam.
• Update: Apple has warned that iTunes voucher scams asking people to make payments over the phone also involve things such as taxes, hospital bills, bail money, debt collection, and utility bills. Members of the public should be aware that calls of a similar nature should be approached with caution, and concerns should be reported to the police.
