Police are investigating 171 reports of £600 energy vouchers being stolen and redeemed without the knowledge of the household they were sent to.
In order to help with rising energy bills, every household in Northern Ireland was provided with a £600 energy support voucher, with some people having the money put straight into their accounts and others needing to redeem the voucher at the Post Office.
When redeeming the voucher, people were meant to provide the Post Office with identification and proof that the person had lived at the address for a number of months.
