Political crime has been most crucial issue of attention to social scientists in Bangladesh because of its severe consequences at social and national level. Everyday newspapers report many incidents of crimes where politically motivated, supported or connected violations of public peace are commonly to be found. If there is no universal definition of political crimes but the violations of laws, order and public peace for political reasons rather individual or public can be defined as political crime. As well as the definition there is rarely found any theoretical basis of political crime but Ross developed a theory after analyzing and combining several theories where political crimes is the result of complex interplay among individuals, situations or opportunities, organizations and resources adequacy. He calls it ISOR relationship. Political crimes related data of 2010 published at a daily Bengali national news paper namely the Prothom Alo has been collected to conduct this research work. These data states that, there are different types and patterns of political crimes in Bangladesh which include political violence in educational institutions, intra-party and inter political party deadly conflicts, attack on law enforcing agencies by political parties, widespread destruction of public properties during the periods of Hartal including vandalism of vehicles, subversive corruption by using political identity, political crimes on tender and development projects, state sponsored violence, environmental hazards for political purpose, attack on opposition by ruling parties and so on. There are several factors behind these types of crimes including economic, social and political. These types of political crimes have severe consequences at social and national perspective of Bangladesh. Finally, immediate initiatives should be taken by government and law enforcing agencies to prevent these subversive crimes. The culture of impunity at the justice system of Bangladesh should be abolished as well as cooperative initiatives of civil society and masses and mass media can contribute to develop a comfortable political crimes free society.
