ABSTRACT 

Paper based system for handling crime reporting becomes one of the challenging methods in police services globally ever since paper was invented. The South Sudan National Police Services (SSNPS) uses this system for handling crime reporting. This system presents a number of challenges such as a delay in disseminating crime reports by victims or witnesses, misplacement or loss of crime recorded files from the Police shelves and inconsistency of suspect documentation due to wrong manipulation or alteration by some individual in the Police offices. Many studies have reached the importance of Police Force in crime report and investigation process; however few researches have focused on how to handle crime report and hence law enforcement agency experienced trouble with methods of handling crime reports. This research work focused on the development of a web-based application for enhancing crime report and investigation in the Police Forces. This is based on qualitative and quantitative approach using cross-sectional design. Both qualitative and quantitative data analysis methods were used for Police departments data including structured questionnaires and interviews with some Police personnel and a thematic analysis was conducted based resulting in emerging coding categories. Then four constructs such as suspect identity/recorded information, crime details, digital and physical evidences were analyzed using questionnaires and interview guide respectively. The results indicated that respondents are concerned about the loss, misplacement and manipulation of the crime details, suspect identity/recorded information, physical and digital evidence respectively in Polices Services. Secondly after the data were analyzed, then web-based application was designed. This was done to illustrate the user functional requirements using unified modeling languages (UML) by envisioning Use case diagrams, activities diagrams, class diagram and deployment diagram. Thirdly web-based application was implemented using PHP, HTML and Java script programming languages and database system using MYSQL programming language. Finally, the web-based application was tested and validated to ensure that its actual requirements and specifications are met. In conclusion based on the finding the researcher recommended that the Police Force need to put more emphasize on effective utilization of crime reporting factors to mitigate and reduce risk of losing evidence, assigned officer is needed to supervise the uses of application implemented in the Police Forces to make sure it is used for right work and moreover organizing training should be done to the Police officers for effective operation and management of the web-based application system.
