The charity bucket was stolen from the Caring Cancer Trust shop on the High Street sometime between midday and 14:00 last Thursday (30th April).
It’s believed it contained around £500 in a mix of coins and notes.
Were you in the area at the time? Did you see anyone suspicious in or around the shop or anyone walking through the area carrying a bucket or anything unusual?
