Databases
PNC contains several separate databases; these include:
- Names File: This contains a large amount of information about people who have been convicted, cautioned or recently arrested (referred to as 'nominals' on the PNC). This includes links to fingerprints and DNA. (The PNC is a text only computer so no graphical information is stored; photos that are taken whilst in custody have information relating to their location so enquiries can be made to obtain a copy of them). Nominals can be placed on the PNC as 'Wanted/Missing' if they are sought in connection with a crime, on warrant and failed to appear at court, AWOL from military service or reported missing. All recent previous arrests and convictions will appear on PNC as well as any impending offences; full disposal history is also included which will show the sentence handed down for each offence. Numerous other items of information are also stored including all previous addresses, co-defendants, local intelligence, marks/scars and descriptions.
- Vehicle File: Provides details on the registered keeper of a motor vehicle, as well as storing other information from the DVLA as to the vehicle's status (Tax Expired, V23 Submitted, Stolen, Chassis Number, Engine Number etc.). Certain reports can be added by the police which relate to the vehicle or occupant status; examples include if the occupants are believed to be involved in crime or are missing, if the vehicle is stolen, if the vehicle is believed to be cloned etc. The vehicle record system is currently linked to the Motor Insurance Database (maintained by the Motor Insurers Bureau) which can confirm if an insurance policy is on the vehicle and the details of such policy such as named drivers, policy dates, policy number and insurance company. The Vehicle Operator Services Agency (VOSA) have computerised the MOT; as a result, a link has been created to the PNC which shows the expiration date of the MOT tests for vehicles. The vehicle file actually contains two separate databases (that show on a single screen), one of which is updated and controlled by the DVLA, and the second part is the responsibility of the police (including vehicle reports, which the DVLA do not have access to).
- Property File: Certain types of stolen and found property can be placed onto the PNC system. These are recorded under the following categories: Trailers (including sidecars), Plant (non-DVLA-registered agricultural and construction machinery), Engines (those that do not fall under other categories), Animal (registered animals), Marine Craft, and Firearms (including imitation firearms).
- Drivers File: This recently added database contains information on 48 million people who either hold a driving licence or are disqualified from holding one. The record will contain information relating to test passes, endorsements and the licence entitlements. This database is the responsibility of the DVLA and is updated every morning.
PNC operators undergo initial training to operate the system which usually consists of a five-day course to view data and conduct simple queries. Further courses are available to expand the user's access level to update and conduct more in-depth queries. Penalties for misuse of the PNC and unlawful access of data are severe; it will likely lead to dismissal and sometimes a court appearance for breaching the Data Protection Act 1998.
A number of criminal justice partners are linked to the PNC, giving them access to the information held on the computer. About 5,000 checks are made each week through the ‘Jurors’ link, which allows Crown Courts to check whether a proposed juror has a criminal record. Previously, the Courts Service struggled to meet its target of randomly checking 20 per cent of potential jury members.
With the growth of trans-national criminality, the PNC was linked to the Schengen Information System (SIS) which shares certain information Europe-wide. This is no longer the case since the UK left the European Union in 2020.
The Police National Computer is one of the main sources of information accessed when a Disclosure and Barring Service check is made. The Police National Computer holds indefinite records of a person's convictions and cautions which will be revealed in a Disclosure and Barring Service check. While of use in informing prospective employers as to the suitability of an applicant for a particular job, the information disclosed can show information which the applicant may think is of no relevance, such as a juvenile conviction for shoplifting where the applicant is now a thirty-year-old individual and applying for a job in a bank. Concerns have been expressed that the indefinite retention of old convictions and cautions is unwarranted. [9]
Because of changes to legislation on 29 May 2013 DBS removed certain specified old and minor offences from criminal record certificates issued from this date. The filtering rules [10] and the list of offences that will never be filtered [11] are available on the DBS website.
A major data loss was discovered in January 2021, and a UK Home Office press release provides information on the extent of the loss and the work to restore the data. [12]
Impact Nominal Index
In 2002 IMPACT delivered a tactical, complementary service to the PNC, called the Impact Nominal Index (INI).
Police National Database
Delivery of the PND (Police National Database) was the first recommendation of the Bichard report. Contractor Logica was awarded a contract of £75M to build and deliver the PND in 2007, but this was not commenced until May 2010 when the first forces began to load their data on to the new system. In November 2010, Northumbria Police became the first force to connect to the PND and to begin to use the new system. From June 2011 all Home Office forces were connected and using the PND. [14]
PND is not a replacement for PNC; as of 2023 [update] it holds 2 billion searchable records, and captures data from 220 different systems from 53 contributing police forces and law enforcement agencies. It is operated by the Canadian company CGI Group, on behalf of the Home Office. [15] CGI bought out the original PND operators Logica in 2012. [16]
The Police National Database aims to: [15]
- Safeguard children and vulnerable people
- Counter terrorism
- Prevent and disrupt serious organized crime
As of the 26/07/2016, the Police National Database reportedly stored 20 million images. [15]
