On the day, a man and woman were purchasing items from the Aldi store in Newbridge Hill.
A mobile phone – namely a Sony Experia – was on the side of the till, and it is reported that the phone was picked up and taken from the store.
The man was described as wearing a hat, green jacket and scarf, and the woman was described as having blonde hair and wearing a dark coloured jacket.
Police are asking if anyone recognises the man and woman in the pictures to let them know who they are, as they may be able to help with their enquiries.
