A thief swiped £60 from a pensioner after he mistakenly left it near a shop till.
The victim had paid for shopping in the Co-Op on Market Street, Carnforth when a man standing next to him took the money.
This week, Lancashire Police released a CCTV image of a man they said they wanted to speak to about the theft, which happened at around 4pm on October 4.
Officers said the man responsible was with a woman with distinctive blonde spiky hair.
Anyone with information is asked to contact police on 101.
