The Dunham Arms, Frodsham. Picture: Google. A pub will have to pay almost £2,500 after the manager was found to be watering down spirits. Jia Tong Chen, 41, manager of the Dunham Arms on Chester Road, Dunham on the Hill, pleaded guilty at the first opportunity to all charges in respect of himself and Dunham Arms Limited of selling spirits which had been watered down. Chester Magistrates Court heard on Wednesday, February 17 there had been no malicious intent behind the offences, and they had been carried out of a wish not to waste alcohol when refilling bottles. Chen and the business were guilty of the same set of nine offences each, with alcoholic drinks found to contain less alcohol than stated on the label.
