JOHANNESBURG - The killer of South African anti-apartheid hero Chris Hani has been stabbed in jail, days after the country's top court ordered him to be released on parole, the prison services said Tuesday.
In a statement, the Department of Correctional Services (DCS) said it was "able to confirm an unfortunate stabbing incident" involving Janusz Walus, who has spent nearly three decades in jail for the 1993 killing.
Walus, a 69-year-old far-right immigrant from then-communist Poland, had been due to be released by Thursday, under an order issued last week by the Constitutional Court that ignited angry protests.
The prison service said without giving details "Walus is stable" and receiving necessary health care.
"It is alleged that Walus was stabbed by another inmate from the same housing unit," it said, adding that an investigation was underway.
A DCS spokesman told AFP the incident occurred "today, in the afternoon."
Walus is being held at the Kgosi Mampuru II Correctional Centre in Pretoria, the spokesman said.
Walus had been handed a life sentence for gunning down Hani, a hugely popular figure and fierce opponent of the apartheid regime.
He was the general secretary of the South African Communist Party (SACP) and chief of staff of Umkhonto we Sizwe, the armed wing of the now-ruling African National Congress (ANC).
He was shot dead in the driveway of his house on April 10, 1993 in Boksburg, a suburb east of Johannesburg.
The shooting occurred just as negotiations to end apartheid were entering their final phase, stoking protests and rioting in black townships that some feared would erupt into civil war.
Then-ANC president Nelson Mandela appeared on national television to appeal for calm, a move that helped ease tensions and open the way to South Africa's first multi-racial elections the following year.
- Parole controversy -
The Constitutional Court on November 21 granted Walus parole and gave the prison service 10 days in which to release him.
Walus "was convicted of very serious crime... cold-blooded murder," said Chief Justice Raymond Zondo.
He "seemed to have been intent on derailing the attainment of democracy by this country," Zondo said.
"His conduct nearly plunged this country into civil unrest."
Even so, said Zondo, the law entitled Walus to parole.
The decision was described as "diabolical" by Hani's widow and unleashed angry protests by the ANC and SADP.
At the weekend, Hani's gravesite and memorial in a suburb east of Johannesburg were vandalised.
In a joint statement with trade unions, the ANC and SACP condemned the attack and said it came in the context of a judgment that "pleased unrepentant apartheid perpetrators."
On Monday, the home affairs ministry announced Walus would have to serve his parole in South Africa, saying he should not be allowed to return home to Poland given the "heinous crime committed."
