Following suspicious circumstances on a sheep farm in Warwickshire, just across the county/Daventry boundary, we are keen to be informed of sightings of a white van challenged by a vigilant farmer on his land. We have full details of the vehicle: it's registration ends VXF and it has writing on the back including a company name 'Plantation Shutters' and we want to speak to the driver/occupants. Enquiries with the bona fide company of this name indicates it has no connection, hence our interest. If seen in Northamptonshire, please report on 101 or 999 depending on the circumstances, quoting Operation Stock (crime reference 1900036556)
