Sample of the study consisted of 600 Nigerians who were over 18 years old and who volunteered to participate in the study. As a result of comprehensive validity and reliability analysis, the scale consists of 14 items and 4 factors called “Illegal execution”, “Indictment”, “Unlawful arrest” and “Intimidation”. Cronbach's Alpha value of the scale was found to be 0.859 and Cronbach's Alpha values for the factors were found to be 0.782 for Illegal execution, 0.714 for Intimidation, 0.728 for Unlawful arrest, and 0.738 for Indictment. According to the results of the validity and reliability analysis, the Extrajudicial Justice Scale can be used as a valid and reliable instrument for Nigerian citizens to determine the influence of extrajudicial justice on the perception people have about the police. Considering that there is no scale used to assess extrajudicial justice in Nigeria, it is thought that this study will guide future research on the subject and reveal its importance for society.
