This project work intends to automate the existing criminal records of  the Nigeria police using Enugu criminal investigating department. The essence was to produce durable criminal records and avoidable lost of criminal records. Structural database management system (DBMS) was used  in  its  development  in  other  to  eliminate  redundancy  in  the compilation, its friendliness in responding to the user exhibits and also its  reliability  and  efficiency  in  tracking  down  criminals.  Another important feature of this system was that it provides user with the facilities  for  having  the  hard  copies  or  print  out  of  any  relevant document as well as the facilities to communication with the system.

Tracking is the observing of persons or objects on the move and supplying a timely ordered sequence of respective location data to a model e.g. capable to serve for depicting the motion on a display capability.  The traditional  and  age-old  system  of  intelligence  and criminal record maintenance has failed to live up to the requirements of the existing crime scenario. Manual processes neither provide accurate, reliable and comprehensive data round the clock nor does it help in trend prediction and decision support.

1.1     Background of the Study

Man by nature is social, gregarious and cannot live in isolation. To maintain peace and harmony in the society, man has to fashion out conduct and some laws  to  govern  the  conduct  of  members  of  the  society.  When  people appreciate  these  codes  of  conduct  and  laws,  protection  of  lives  and properties are guaranteed.

Generally tracking is the observing of persons or objects on the move and  supplying a timely ordered sequence of respective location data to a model e.g. capable to serve for depicting the motion on a display capability. The  traditional  and  age-old  system of  intelligence  and  criminal  record maintenance has failed to live up to the requirements of the existing crime scenario. 

Manual  processes  neither  provide  accurate,  reliable  and comprehensive data round the clock nor does it help in trend prediction and decision  support.  It  also  results  in  lower  productivity  and  ineffective utilization of manpower. The solution to this ever-increasing problem lies in the effective use of Information Technology. Crime Tracking Information System uses computer-generated records as an interface for integrating and accessing massive amounts of location-based information.


Crime  tracking  system  allows  police  personnel  to  plan  effectively  for emergency  response,  determine  mitigation  priorities,  analyses  historical events, and predict future events. Crime tracking system helps identify potential suspects to increase investigators suspect base when no leads are evident.  The  ability  to  access  and  process  information  quickly  while displaying it in a spatial and visual medium allows agencies to allocate resources quickly and more effectively.

In the mission-critical‘ nature of law  enforcement,  information  about  the  location  of  a  crime,  incident, suspect, or victim is often crucial to determine the manner and size of the response.  Crime  tracking  software  helps  co-ordinate  vast  amounts  of location-based data from multiple sources. It enables the user to layer the data and view the data most critical to the particular issue or mission.

It is used world over by police departments, both large and small, to provide solutions for crime analysis, criminal tracking, traffic safety, community policing, Intranet/Internet mapping, and numerous other tasks.

Crime tracking system helps crime officers determine potential crime sites by examining complex seemingly unrelated criteria and displaying them all in an interface. It also helps them map inmate populations, fixtures, and equipment to provide for the safety of inmates by separating gang members, identifying  high-risk  or  potentially  violent  inmates,  and  identifying hazardous locations in an area. It reduces the potential for internal violence  by providing better command and control.

Traditionally, these activities have been supported by paper and pen. Police officers now have the ability to immediately generate crime report directly relevant to the situation at hand. Police agencies collect vast amounts of data from many sources including  called-for-services, arrests,  first  information  reports  and  daily report. The same information provides a powerful decision making tool for investigators, supervisors, and administrators.

1.2     Statement of Problem

The Nigerian Police, which is used as a case study, has an existing criminal Tracking System, but this system is not automated. The documentation of criminal records is done on paper and pen. The storage of these criminal records is not something to write home about.

Case files are dumped in heaps while some are kept on shelves. With the  moldy nature of the state such important documents quickly get dusty and  because of lack of proper storage, some criminal documents are seriously  damaged by rats that feed on them. With this kind of situation, it becomes  highly difficult if not impossible to track down known criminal, access past  criminal history of a suspect and know the status of some concluded cases.


1.3     Purpose of the Study

The project intends to computerize the existing Criminal Tracking System at the Nigerian Police. Specifically, the project will accomplish the following:

1) Design and develop a central database system that would serve as statewide repository of criminal data. The smaller database system at the sub-police station will be networked to the central database to access criminal data on cases not handled at the local station. This database system will be updated by local police station within the state as well as the police headquarters. (acting as a criminal data collection centers)

2)      The central database system will be resident on a server at the police headquarter and will be linked to both the local police station  and  the  Central  Criminal  Registry  via  a  client-  server between  station  as  well  as  Criminal  Justice,  the  rendering  of Criminal Justice.

3)      The database system will capture detailed information about crime suspect right from the time the crime was reported at the police down  to  the  point  the  suspect  appears  before  the  court  for prosecution as thereafter.

4)      The systems will posses features that will enable criminal data to

5)      be purged from the system, updated and queried.

1.4     Justification

Implementation of a crime information system by the Nigerian police will help the police and the masses to get useful information on individuals with crime records. The system developed will among other things:

  1. Maintain a database of all crime records
  2. Enable a quick search on the database to retrieve crime information
  3. Enable Nigerian police to track previous crimes committed by as suspect
  4. Make crime control easier for the police
