Port of Portland Police (United Kingdom)
The Port of Portland Police is a body of special constables attested under section 79 of the Harbours, Docks, and Piers Clauses Act 1847. It was established in 1997 when the Portland Harbour Authority Ltd. bought the port from the British Government. The act uses the term 'special constable'; at the time this act was passed 'special constable' meant any constable who was not a member of a territorial police force
