Corruption-convicted former top cop Jackie Selebi was expected to be released on medical parole from Steve Biko Hospital in Pretoria on Friday, Correctional Services Minister Sibusiso Ndebele announced.
"Mr Selebi will be going home today [Friday]," he told a media briefing in Pretoria.
"The department has limited capacity to provide for [the] palliative care needed by some offenders," said Ndebele.
Palliative care meant he would be kept comfortable until his death, as there was no hope of him recovering.
Ndebele said the medical parole advisory board convened in Pretoria on June 20 and deliberated on the fate of 12 applications by offenders.
"Six offenders were recommended for medical parole. Of these, two of the offenders were respectively released on the 9th and 12 of July 2012.
"Three offenders' applications were turned down. Mr Jackie Selebi will be released today and another offender is expected to be released next week," he said.
"Three offenders died whilst the documentation was being processed."
Selebi was president of Interpol at the time of the investigation into claims that he received money from convicted drug trafficker and police informer Glenn Agliotti.
He was convicted of corruption on July 2, 2010, and handed a 15-year jail sentence.
Selebi appealed against the corruption conviction in the Supreme Court of Appeal. In December 2011 he collapsed at home in Waterkloof, Pretoria, while watching the appeal judgment on television. His appeal was denied.
This meant he had to begin his 15-year jail sentence for corruption. It was decided he would stay in Pretoria Central Prison's medical wing indefinitely.
At the time he had not instructed his medical team to apply for medical parole. Selebi had also been trained to administer his own treatment.
He suffers from diabetes and kidney disease.
