DESIGN
AND IMPLEMENTATION OF COMPUTER BASED POLICE INVESTIGATION SYSTEM
(A
CASE STUDY OF FIIB HEADQUARTERS OGBOR-HILL ABA)
ABSTRACT
The world over, it is indisputable that the introduction of computer technology
in different facets of life, has virtually transformed and entranced
information processing, which is very vital in any organization or parastatals
of government. Not only as a means of information processing, the
technology has also proved to be the fastest means of information retrieval,
which forms the nucleus of this study.
This work tries to x- ray the rate role of the computer in crime investigation
as it affects the Nigerian police. Force it looks at ways of improving
the information management of the force. This research work will cover
the following areas: record information retrieval relating to MIS (Management
information system), retirement Cretan for officers and crime mapping through a
data bank of crime related information.
A detailed design of a computerized approach that will bring the much needed
innovation is given. Also included in this work is a praper documentation
for the new system design.
ORGANIZATION
OF THE WORK
This project work is organized in seven chapters. Chapter one begins with
an introduction of the project, a brief statement of the problem, the purpose
of the study. It explicitly outlines the aims and objectives. Also
the scope, limitations and constrains are also discussed. It ends finally
with definition of terms; chapter two is specifically dedicated to literature
review pertaining to the project work chapter three of the project opens with
the description and analysis of the existing system. The fact-finding
methods employed for the project is documented. The objectives of the
existing system are highlighted, and the input, process and output analysis
discussed the information floe diagram is shown, and the problems of the
existing system and the justification for the new system discussed.
Chapter four discussed mainly the new system design. The output
specification and design and file design are respectively highlighted, also the
procedure chart and system flowchart is illustrated. It closes with the
system requirement.
Chapter five discusses the implementation of the new system. The program
design, which consists of the program flowcharts and the corresponding pseudo
code, are all highlighted. The source program is written and a test run
is carried out.
Chapter six dwelt on the documentation of the Q basic program for the new
system. Chapter seven finally closes with recommendation and
conclusion. Attached to this work are the FIIB (Federal Intelligence and
information Bureau) organization structure, the input and output forms for
suspect confirmation the references made to during research work are
lighted.

ONE
INTRODUCTION
Information Technology (IT) has set a new world order turning the world into a
global village, where information plays an indispensable role.
The Federal Investigation and Intelligence Bureau (FIIB), is a special outfit
of the Nigeria police force, as a role similar to that of the FBI (Federal
Bureau of intelligence) of the united states (US) information they say is an
indispensable force, and if we should go by this maxim, it buttresses the need
at which classified information is to this outfit.
Over the years, this outfit had made tremendous impact in combating crime, but
in recent times, there has been an avalanche of crime wave in the country leading
to insecurity of life and properties close investigation concerning crime
activities reveals that this special outfit of the police force is bedeviled
with obsolete equipment.
Despite the glint strides taken by this outfit over the years changing their
investigation and recording equipment to tape storage using cassette as
recorder, there are still a lot of surmountable problems which has hitherto,
reduced the efficiency Bureau, Ogbor-Hill, Aba and other division of the outfit
through out Nigeria. The panacea to this may no doubt; lie in the
introduction of a properly designed computer base system which will bring the
much-desired automation hence, a prerequisite for being a member of the new
world order vis-Ã -vis information technology.
1.1 STATEMENT OF THE PROBLEM
The statutory duty of the federal investigation and
intelligence Bureau (FIIB) is crime prevention and intelligence network which
is solely based on information. This information received from conducted
investigation, which should be supplied to the Bureau within minutes using
electron communication. But this takes days or weeks and sometimes months
if the investigation is carried in a distant area. The storage medium
currently at disposal for information is susceptible to unauthorized access and
damage. Most often, the recorded information is usually not within the
reach when needed. Going by this high level of graft in the country,
officers can easily remove: recorded information of a very serious crime
activity by mere bribe offer. In view of the above problems w3hich have
attracted the author’s attention, he has unequivocally, decided to design a
computer base system which will correct this abnormalities.
1.2
PURPOSE OF THE STUDY
Having
been aware of the numerous anomalies which have reduced the efficiency of the
Nigeria police force (NPF), the purpose of this research is focused on
designing an developing a computerized based or approach to information storage
and retrievals against the manual approach, as it affects the (FIIB) federal
intelligence investigation Bureau), and the Nigeria police in general.
1.3 AIMS AND OBJECTIVES
The
aims and objectives of the research work centers on the following:-
-
To show case the merits of a
computerized system in police investigation and intelligence.
-
To upgrade the information network
system of the Nigeria police force
-
To enhance speedy and reliable
information retrieval in crime records.
-
To identify areas where computers can
be used in detective work.
-
To investigate the possibilities of
using the computer to analyse and compare substance taken from the scene of
crime.
-
To establish the possibilities of using
the computer in crime mapping – A situation where data concerning crimes that
have been committed in a certain area is fed into a computer and then, the
computer produces a map that shows whether it is any pattern to the crime.
1.4
SCOPE OF THE STUDY
This research work is limited to the federal investigation
and intelligence Bureau (FIIB) Ogbor-Hill Aba, Abia state although this outfit
has just been moved to Calabar, Cross River State. The choice of
investigation and intelligence was chosen due to the fact that there are certain
information, which are not meant for public consumption.
