Former police commissioner, Jackie Selebi was discharged from hospital this week, and transferred to the Pretoria Central Prison.
Sapa reports that Selebi was moved from the Steve Biko Academic Hospital to a cell within the prison's hospital unit.
The deputy commissioner of correctional services, Zacharia Modise, says Selebi will be monitored closely by two trained nurses.
The former police chief collapsed at his home in Waterkloof, Pretoria, in December, and was admitted to hospital, after losing his appeal against a corruption conviction in the Supreme Court of Appeal last year.
