I have lost my Grandfather's ring. I am deeply saddened as this item is extremely sentimental as he has passed away and this is all I have remaining of him to remember him by. He was Irish and my Mum gave me the ring just before St. Patrick's Day this year. The first thing my Mum said to be was 'don't lose the ring', as she has cherished it for many years. Please can anybody let me know if you have come across the ring. I will be unfathomably grateful and I am offering a generous reward for anybody who returns the ring. Thank you kindly, Declan

Gold ring lost in City Park, most likely in the park with the musical instruments (the step pads that make sound) or somewhere from there towards the large climbing frame park.
