Police are investigating a number of cases where £600 energy vouchers have been "illegally redeemed" in Northern Ireland.
In order to help with rising energy prices, households across Northern Ireland that use prepaid metres were sent £600 vouchers, with those on direct debits having their £600 paid directly into their accounts.
However, some of these vouchers have been taken by people they were not intended for and redeemed without the knowledge of the customer.
