Street children 68. The Committee is extremely concerned at: (a) The increasing number of street children and unacceptable policies and programmes implemented by the juvenile affairs services to address this situation; (b) The special preventive sweeps such as “Lesson”, “Street children”, “Railway station” and “Holiday” and at the keeping of a special data base of information on these children which is being considered as social assistance aimed at preventing abandonment and criminality; (c) The vulnerability of street children to, inter alia, sexual abuse, violence, including from the police, exploitation, lack of access to education, substance abuse, sexually transmitted diseases, HIV/AIDS and malnutrition. 69. The Committee recommends that the State party: (a) Ensure that street children are provided with adequate nutrition, clothing, housing, health care and educational opportunities, including vocational and life-skills training, in order to support their full development; (b) Ensure that street children are provided with services that promote physical and psychological recovery and social reintegration; (c) Undertake a study to assess the scope and causes of the phenomenon and consider establishing a comprehensive strategy, to address the increasingly large number of street children, with the aim of preventing and reducing this phenomenon in the best interests of these children and with their participation; (d) Consider addressing the situation of street children within the system of youth social welfare services rather than juvenile affairs services.
