People withdrawing money have been urged to be vigilant after a 'skimming device' was found at a cash machine in Oswaldtwistle.
A customer went to use the machine outside the Co-Op store on Union Road when the card was swallowed.
An examination by a member of staff found a skimming device attached to the card reader.
The device is used by criminals to capture data and empty bank accounts.
Police said the customer was unable to retrieve his card however no money was stolen during the incident on February 18.
A similar device was also found two days earlier at a Co-Op machine in Colne.
The machine also swallowed his card and after walking away another man approached the ATM to withdraw money from his account before walking away.
PC Jayne Chambers of Burnley police said: “We would urge people to be vigilant when using cash machines and if you spot anything at all that you feel is unusual, do not use the machine and report it to the owner of the machine.”
Anyone with any information about this incident should contact Lancashire Police on 101 quoting log number LC-20140218-1169 for the Oswaldtwistle incident.
