Security challenges is one of the major social problems confronting not only Sokoto Metropolis or Nigeria in general, but most of the third world countries and some other parts of the world. Street children are often found to be active participants in most of the social uprisings that were witnessed in some parts of Nigeria, particularly Sokoto metropolis. The quest to find out why and how the number of street children is increasing and how it affects the level of security prompted the conduct of this research work. In the course of the research, qualitative research technique was adopted. Focus Group Discussion and key informant Interviews were the methods through which data were gathered. The data were presented in narrative form (prose style) whereas content analysis was used in the interpretation of the data. Social disorganization theory was used in as the theoretical framework. The research work found poverty, unemploymentand poor and inadequate learning facilities as the major contributors to the escalating number of street children. In the course their day to day activities, the street children were found engaging in some delinquent activities such as theft, smoking and sexual practices etc. during any social upspring, they were found to be active participants and consequently, increase the rate of material and human damages. It was also found that solutions to the increasing number of street children revolve around family, community and government efforts. The researchers recommended employment generation, less family reliance on children and formulation of some welfare policies as the solutions to the increasing number of street children and their implications generally.
