Policing in the county can be traced back to Brighton Borough Police established in 1830. A few years later on 13 March 1844 Chief Constable Henry Solomon was murdered in his office by a prisoner he was interviewing. He is believed to be the only chief officer to have suffered such a fate. Prior to 1830 local watchmen were appointed to provide some degree of law enforcement in the area. In 1812, there were some 12 watchmen who were responsible for the town. By 1814 the number had grown to 28 and at this time the title of constable was in use for them. By 1868 the force had grown to 100 officers and helmets replaced top hats. In 1918 the first woman was appointed as a police officer in this force and by 1930 it had grown to 216 officers. On 14 September 1933, Brighton Borough Police were the first force to introduce police radios.
