The group included homeless persons, the mentally ill, sex workers, factory and construction workers, and children. Similar cooperation during previous summits had resulted in the release of these individuals, where appropriate, to the care of non-governmental organizations. OHCHR proposed technical assistance to the Municipality of Phnom Penh to put in place a process to avoid similar instances of arbitrary detention in the future. 52.
