Criminal victimization against agent bankers and their customers has recently been on the increase, and the multiplier effect is a major socio-economic problem that could cause a downturn in the economy. This study examines the exposure of agent bankers and their customers to criminal victimization in Ado city, Nigeria. Specifically, the study explores the forms of criminal victimization against agent bankers and their customers, examines the consequences of criminal victimization, looks into the cases of agent bankers and customer victimization, and determines the preventive measures adopted by agent bankers and their customers against victimization. Lifestyle-routine activity theory was deployed as the conceptual framework. An exploratory research design and snowball and purposive sampling with key informant and in-depth interviews were used to interview 12 victimized and non-victimized agent bankers and their customers. Interviews were conducted in Fayose market, King market, Bisi market, and Irona market. Findings reveal that agents’ bankers and their customers were being targeted by criminals who use non-violent tactics. The eagerness of the agent bankers to transact business brings a measure of carelessness to their business dealings. This carelessness and lack of security measures exposes them to motivated offenders. Victimization through fake alert, fraudulent transfer, withdrawal under false pretense, fraudulent alteration, intentional criminal patronage, fake identity, and urgent withdrawal under duress represent the themes found. It is imperative for agent bankers and their customers to set up security measures that could protect them against being victimized.
