Windsor (The Daleks' Master Plan)

Windsor (PROSE: The Mutation of Time) was the Detective-Inspector in charge of the Criminal Investigation Department at the Liverpool police station where the First Doctor landed his TARDIS on Christmas Day, 1965. When the Doctor exited the TARDIS, a policeman arrested him and brought him inside the station, whereupon the station sergeant sent him back to CID to meet with the Detective Inspector.

Steven Taylor, wearing a stolen police tunic, convinced the Detective Inspector that the Doctor was a harmless nutter with whom G Division was familiar. (TV: The Daleks' Master Plan)

Behind the scenes
In the novelisation, he is given the name Windsor. This is in reference to Frank Windsor, who played a detective inspector in the series Z-Cars. During the original production of The Daleks' Master Plan, a crossover with the cast and setting of Z-Cars had been intended for the police station scenes, until the idea was rejected by Z-Cars producer.
