The incident happened when a man with a black and white dog entered a shop in Madeley at around 6am on October 29.
A number of items were deliberately damaged and the shop manager was abused with racially offensive language, West Mercia Police said.
The force has now released a CCTV image of a man officers say "they wish to speak to".
The suspect is pictured holding a newspaper in one hand and a dog's lead in the other, with other newspapers scattered on the floor behind.
A spokesman for West Mercia Police said: "Officers would like to speak to the man pictured as it’s believed he may have information which could assist with enquiries."
