The world over, it is indisputable that the introduction of computer technology in different facts of life has virtually transformed and entranced information processing, while is very vital in any organization or parastatals of government only a means of information processing, has the technology also proved to be the fastest means of information retrieval, which forms the nucleus of the study. This work tries tox-way the rate role of the computerized security information system 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 area record information system retirement creating 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 paper documentation for the neo system design.
ORGANIZATION OF 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 outline the aims and objectives. Also eh scope limitation and constraints are also discussed. It ends finally with definition of terms. Chapter two is specifically dedicated to literature reviews pertaining of project work. Chapter three of the project is documented. The objectives of the existing system are highlighted, and the input, process and output analysis discussed the information flow diagram is shown, and the problems of the existing system and the justification for the system discussed. Chapter four discussed mainly the new system design, the output specification and design 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 flow charts and the corresponding pseudo codes, are al highlighted. The source program for the new system. Chapter six finally closes with recommendation and conclusion. Attached to this work are the police (Federal Intelligence and Information Bureau) organization structure, the input and output forms of suspect confirmation the references made to during research work are highlighted.

INTRODUCTION
Information Technology (IT) has set world order turning the world a global village, where information plays an indispensable role.
The federal security information (police) 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 meaning it buttressed 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 advance of crime wave in the country leading to insecurity of life and properties close investigation concerning crime activities reveals that the special outfit of he police force is bedeviled with absolute equipment.
Despite the glint strides taken by this outfit over the years changing their investigation and recording equipment to tape storage cassette as recorders, there are still a lot of surmountable problem which has litterto, reduced eh efficiency bureau, Ogbor-Hill, Aba and other division of the outfit through out Nigeria. The panacea to this may no doubt, le in the introduction of a property designed computer base system which will bring the much desired automation hence a prerequisite for being a member of the world order vis-a-vas information technology.
1.1 STATEMENT OF THE PROBLEM
The statutory duty of the federal security and information bureau (police) is crime prevention and intelligence network while is solely based on information. This information received from conducted investigation, which should be supplied to the bureau within minutes using electron communication. But the take days or weeks and sometimes months if the investigation is carried in a distance 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 eh reach when needed. Going by this high level of graft in the country officers can easily remove recorded information of every serious crime activity by mere bribe often. In view of eh above problems which have attracted the author’s attention, his unequivocally decided to design a computer base system which will correct this abnormalities.
1.2 AIMS AND OBJECTIVES
The aims and objectives of the research work centers on the following;
1.3 SCOPE OF THE STUDY
This research work is limited to the federal security information bureau (police) Ogbor-Hill Aba. Abia although this outfit has just been moved to Calabar, Cross River state. The choice of security information which are not meant for public consumption.
1.4 LIMITATION
Investigation for facts about this research work has fraught with the following constraints.
ISSUE OF CONFIDENTIALITY
This work is a dicey one that concentrates on issues considered confidential the outfit chosen for investigation could not disclose or rather give access easily to the relevant information. Security information needs high level of secreting. Segual to the approval for data collection comes after services of consultation with important personnel of command.
TIME
Time factor is another major constraint, which unequivocally did force me to limit the scope of work. The time stipulated for actual competition of this work is ratted too short to cover all relevant sections of the command. Also, the researcher had to spend some time before approval fro investigation was given.
FINANCE
Intended to make comprehensive excerpts from some foreign journals on issues bothering on crime security information network but due to financial constraint, I could only limit myself to a few within my reach. Also, the cost of shuttling to the new areas command of the outfit also constituted a big source of financial stress.
