Police have issue a warning about bogus door to door sellers operating in the district.
The salespeople claim to be either ex-forces personnel or reformed criminals trying to redeem themselves.
The callers are not legitimate however, Richmondshire police say.

A police spokesperson said: “If you see anything or anyone suspicious in your area please call us and report immediately.
“We do need to catch them to be able to deal with them.”
Anyone with information should call 101.
