5.2. The Medium A centre started operating in 1997 and was designed in accordance with unit management principles. It comprises amongst others an admission centre, six housing units (cell blocks), a hospital unit, a pre-release unit, textile workshops, sports fields and classrooms. The Medium B centre, a much older structure, was 213% overcrowded at the time of the visit. It has none of the facilities available at the Medium A centre and the remand detainees housed there spend most of their time in the grossly overcrowded cells. The Medium A centre, designed to house 1 338, housed 1 348 sentenced offenders at the time of the visit, while the Medium B centre designed for 175, housed 382 remand detainees.
