Although Helston was mandated to create an organised police force, it continued to appoint parish officers until the 1850s when the increase in population and crime rate demanded the appointment of a full time head constable and a handful of part-time constables.
A popular pastime among drunken miners in Helston was the attempted strangulation of Head Constable Bishop, who found himself being throttled on many occasions while attempting to make arrests.
The force was amalgamated with the Cornwall Constabulary in 1889.
Information from Slates Directory 12 / 1852 states that the town prison was in Wendron Street and that the Gaoler was Thomas Richards.
The Helston Council Minute Book held in Helston Museum in 1957 records the following information:
|3/8/1860||Mr Fitzsimmons was dismissed from office of policeman and gaoler for neglect of duty.|
|24/8/1860||Mr Fitzsimmons was reinstated as a policeman upon promising to be more cautious in the future.|

|1863||A list of Constables was recorded as being appointed by West Kerrier Petty Sessions on 23/3/1863, this consisted of 41 constables and eight special constables.|
|1886||The Cornish Telegraph newspaper records the incident of a murder at Breague.|
