It is reported that a total of 60 officers from the New York Police Department died from suicide due to mental health disturbance and approximately 95 police officers in China died on the frontline of fighting this outbreak. Thus, it is important to provide appropriate mental health services and to be able to do such, there is the need to understand the psychological risk factors and their subsequent needs during pandemic. The main purpose of this study is to identify the impact of COVID-19 pandemic to mental health of Malaysian police officers. Methods & Materials: Police Stress Questionnaires (PSQ) was used to measure the police-specific stressors related with COVID19. Meanwhile, Depression Anxiety Stress Scale (DASS-21) questionnaires use to determine the prevalence of occupational stress among police officers. Results: It is found that the highest percentage reported of 41.1% moderate depression, 45% of moderate anxiety and 31.8% moderate stress among the respondents. Lack of resources, unequal sharing of work responsibilities, inadequate equipment and high risk to COVID-19 infection are associated with depression, anxiety and stress among police officers. There is significant correlation between COVID-19 stressors and level of depression, anxiety and stress among the police officers with direct correlation. Conclusion: Majority of the police officers suffer moderate to severe depression, anxiety and stress during COVID-19 pandemic.
