Morrisons shoppers have been warned about a fake voucher scam which asks for their bank details.
Scammers are using e-mails, text messages and social network sites like Twitter and Facebook to give shoppers the opportunity to get £40 worth of free vouchers.
However, the fake offer aims to catch customers out and provide personal bank details to the con artists responsible.
The supermarket warned its customers about this on their Facebook page.
A spokesman said: “We are aware of a number of spam e-mails, text messages and social media posts, from third-parties posing as Morrisons, for the purpose of fraudulent activity.
“If you receive one of these suspicious messages, please do not click any links, open attachments or enter personal information.
