Criminal History System (CHS)
The Criminal History System (CHS) is a dynamic database and interactive investigative tool which plays an important role in day to day policing. It provides the operational police officer with essential information on a person under enquiry. Essentially it is an index of records about individuals who have a criminal record. This information includes details such as names, aliases and known addresses.
It is used for administrative purposes to record details of those people who are firearm, shotgun dealer and explosive certificate holders. It also contains information on long-term missing persons.
