 In one of the very first episodes, Sergeant Blaketon stated that the Ashfordly police force comprised 12 officers, but storylines never built on this fact, and only four (or at times five) officers ever featured in the show.These are the Ashfordly sergeant, the Aidensfield village constable of the day, plus Phil Bellamy (later replaced by Don Wetherby), Alf Ventress (later in a civilian capacity), and, from time to time, another rookie PC.Occasionally other anonymous police officers are seen in the background (for example when the force is required to police a large demonstration or undertake a search of the moors), but they are never given names or any dialogue.
