Police are warning treasure hunters to mind the law after an incident in Plympton St Maurice. Plympton officers began an investigation after witnesses claimed they saw a man acting suspiciously in the grounds of Castle Green in Plympton St Maurice in the early hours of Sunday, February 8. Pc Greg Rendle, neighbourhood beat manager for Plympton said the man was seen wearing a head-torch and metal detecting in the area. At one stage he was seen to retrieve what appeared to be coins from the ground. Pc Rendle said: “Castle Green is a protected ancient monument under the control of English Heritage and metal detecting within this area is an offence. “Our enquires have identified a suspect and he is being dealt with by English Heritage and Plympton police. “It is important that our community remain vigilant at all times and report any suspicious behaviour to the police on 101.”Of course most detector users are law abiding - except the ones that are not.
