The Saskatoon Police Service is looking for two suspects involved in a card skimming operation in the city.
Police say the men wait for the sales clerk at a business to look away and then tamper with the debit machine. They return a few days later to retrieve the data.
So far the pair is suspected in at least five cases in the city and others across the province.
Police are reminding businesses to carefully watch their Point of Sale terminals.
Anyone with information can contact Crime Stoppers at 1-800-222-8477
