The six men – who appear to be looking straight at cameras and giving a “thumbs-up” sign in some cases – were caught on lens at Wirksworth’s Co-op petrol station on August 22.
A police spokesman said the men could have been photographed while at tills and petrol pumps – and the images here are still captures of their movements.
They want to speak to men in connection to repeat offences linked to bilking.
Officers say members of the public should not approach anyone who they believe to be shown in the images but should contact Crimestoppers on 0800 555 111.
Anyone who can identify any of the males shown should quote the reference number accompanying the picture.
