Police are investigating allegations that dozens of Tesco customer Clubcard accounts may have fallen victim to online fraud.
Club card is Tesco's customer loyalty scheme in which shoppers get points that can be converted into gift vouchers. Tesco currently has around 16 million Clubcard members.
The supermarket said it was also conducting an internal investigation into "a small number of incidents" where Clubcard vouchers are alleged to have been stolen from online accounts. A handful of consumers affected by the alleged theft have been reimbursed.
Among the complaints made by customers are reports that users logging into their Clubcard online accounts have found hundreds of pounds worth of vouchers missing, while others have been unable to log on.
A Tesco spokesperson said: "We have launched a thorough investigation into a small number of incidents and referred the matter to the police. In the meantime, we'd like to ask any customers who believe they're affected to contact us directly so that we can make sure their accounts are up to date."
