Abstract
Dealing with transnational crimes present certain unique and pressing challenges to national criminal justice systems all around the world. States have individually embarked on legislative and procedural reforms, training and capacity building initiatives to combat the complexity of activities of transnational crime actors. These efforts have been met with setbacks as the nature of transnational crimes often require interrelations between states in investigating and prosecuting transnational crimes. The involvement of the international community to ensure cooperation among states in this regard becomes inevitable. This paper examines the investigative and prosecutorial approaches in combating international crimes, and calls for the adoption of more proactive investigative approaches with long term control guarantees and due regard for human rights.
