In the West African sub-region, the trend of trafficking in persons is widespread; and the phenomenon now attaining its peak unhindered, has actually portrayed Nigeria as a nation occupying a central position as an originating state, transit and destination for victims of trafficking. There is also evidence of internal trafficking from rural zones to cities. The menace of human trafficking in Nigerian state has taken an indescribable facet in the last two decades owing to the factors of; massive unemployment, poverty, recession in the economy, conflicts, globalization, existing weak legal system, and inadequate legislation, and political will. Trafficking in person is an organized crime and a modern form of slavery. The two methods used by traffickers to get their victims are deception and through force. Human trafficking has continued to strive in Nigeria because of shameful connivance among the Nigeria’s security agencies, Embassies, airline officials and human traffickers. The study adopts Marcus Felson and Lawrence Cohen’s Routine Activity and the Kevin Bales’ Modern Slavery theories (1979; 1999). 500 copies of questionnaire were administered to a set of purposively selected respondents with the In-Depth Interview Guide to elicit information on the subject. The study in its findings reveals that human trafficking has continued to strive in Nigeria because of connivance from the security, immigration, embassy, airline officials and traffickers while the menace has put Nigeria’s identity black in the global system. The study therefore recommended that the Nigerian government should swiftly endeavour to address the issue of massive unemployment and poverty in the state as well as create enabling environments for entrepreneurship for the citizenry; also the national laws, international conventions and protocols that have legal potencies to curb trafficking must be implemented or strengthened; and finally, fighting human trafficking in Nigeria requires more efforts to create public awareness of the crime, organize counseling, rehabilitation and re-integration program for the victims.
