Police are warning businesses to be wary of people asking to exhange large amounts of cash into smaller denominations. A few incidents have occurred recently whereby people have wanted to change large numbers of £20 notes into £10 notes and then back again. This has resulted in the cashier becoming confused and the individuals not handing back the full amount of cash. Narberth police are aware of the matter and anyone with information is asked to contact them on 0845 330 2000.
