Over the years and as the population grew, so did the police force. In 1872 responsibiity for the force was transferred to a Board of Police Commissioners. In 1973 the Hamilton Police Force was replaced by the Hamilton-Wentworth Regional Police. The fonds consists of arrest records for January 1882 to December 1885.
