Mangaung Prison, the second-largest private prison in the world, is under investigation by the South African government for using forcible injections and electric shock treatment to subdue inmates. A year-long investigation by the journalism department of the University of Witwatersrand found that the medical staff regularly injected inmates with antipsychotics (including Risperdal) as a means of controlling behavior. Prison officials defended use of the drugs, which are known to cause memory loss, muscle rigidity, strokes and other serious, potentially life-threatening side effects.
