Abstract
The Law enforcement agencies like that of police today are faced with large volume of data that must be processed and transformed into useful information and hence data mining can greatly improve crime analysis and aid in reducing and preventing crime. The purpose of this study is to construct predictive models that could help in the effort of crime pattern analysis with the aim of supporting the crime prevention activities at the Hossaena town police office. For this study, a six-step hybrid knowledge discovery process model is followed, due to the nature of the problem and attributes in the dataset. The classification technique such as J48 decision tree and Naive Bayes used to build the models. Performance of the models is compared using accuracy, True Positive Rate, False Positives Rate, and the area under the Relative Optical character curve. J48 decision tree registers better performance with 96.34% accuracy. Lastly for extracting the knowledge the researcher develop the prototype for the user for support the decision which crime is assigned under the serious, medium or low for this purpose the researcher generate the prototypes.

Highlights
Data Mining or Knowledge Discovery in Databases (KDD) in simple words is nontrivial extraction of implicit, previously unknown, and potentially useful information from data
The purpose of this study was to explore the applicability of data mining techniques in the process of crime prevention for the Hossaena Police office
The models were built on the preprocessed crime prevention dataset with two different supervised machine learning algorithms i.e. J48 Classifier and Naïve Bayes using Weka 3.8 machine learning software
Summary
Data Mining or Knowledge Discovery in Databases (KDD) in simple words is nontrivial extraction of implicit, previously unknown, and potentially useful information from data According to Berry and Linoff (1997) Data mining is one such tool that has evolved to play a role as an instrument to discovery patterns buried in large databases. It is obvious from the outset that to make use of data and records, relevant data have to be kept and managed properly. For this reason the Hossaena town police office have been collecting criminal records since its establishment and have maintained numerous criminal records consisting of fingerprints, names, photographs, and general descriptions of criminals. Human beings want to live and labor in a place where they are safe They want to ensure that there is a worried body that defends their lives as well as their belongings from possible risks. Faraway from creation and performing of laws for the avoidance of crime, governments must start agencies and establishments, which apply these laws
