Abstract
The present article highlights ethical challenges and practical solutions to the problems that arise when designing and conducting the fieldwork data collection with the members of violent youth gangs, prison inmates, and arrestees held in police cells in Nigeria. Issues related to the process of seeking approval and then implementing the research, gaining access, achieving informed consent, confidentiality, the use of interpreters, and remuneration are presented through case studies. The conclusion stresses the need for researchers to be well prepared and sensitive to the research participants' community and cultural backgrounds while following ethical practices in multicultural contexts, especially in Africa and other developing nations
