Irish Police Gazettes, 1861-1893 to its database. This twice-weekly paper, better known as the 'Hue and Cry', was the official publication of the Royal Irish Constabulary (RIC) and was a means to communicate secretly between members of the police divisions.
The online collection comprises 150,000 indexed entries covering 28,353 reported crimes, 28,092 reports of breaking of License conditions, and 23,345 reports of theft. It is full of missing persons (including army deserters), wanted criminals, habitual criminals and details of those who had been apprehended.
In addition, all editions published during the stated 32 year period can be browsed.
Among the entries are reports of stolen heifers and the like, which might be of minor interest if the owner was an ancestor, but the level of detail in some of the reports of more serious crime can be outstanding.
Take this example from 9 July, 1878:
