A woman was in Grantham town centre when her bank card was stolen from her coat pocket.
The card was later used at the Asda in Union Street, Morrisons and Poundland at the Isaac Newton Centre and Max off-licence.
Lincolnshire Police is now treating the incident as fraud by false representation.
The force has now released CCTV of two men they would like to speak to and said they “may be able to help with the investigation.”
Anyone who recognises the two men has been urged to call 101 and quote incident 380 of January 22.
