Correctional Services said that “matters are under control” at Johannesburg’s Sun City Prison on Wed.
Detectives investigating the murder of Bob Woolmer, pictured, are appealing for information from fans and tourists who are, or were, in Jamaica for the Cricket World Cup.
The island nation's deputy police commissioner, Mark Shields, has asked tourists who have returned to their home countries to dial the international hotline +1-876-927-5000 or contact their local police.
Woolmer's murder, it is now believed, might takes months or even years to solve.
His body was found in his room on the 12th floor of the Jamaica Pegasus Hotel, in Kingston, on March 8.
The 58-year-old former Proteas coach was said by the police to have been murdered in "evil and extraordinary" circumstances, probably by someone he knew.
The murder has triggered conspiracy theories about match-fixing, with several former players speculating that Woolmer was killed to prevent him from speaking out.
Shields, a former Scotland Yard man, acknowledged that match-fixing links "keep coming to light".
Shields has dismissed comments by Pakistan spokesman Pervez Mir that detectives had cleared the members of his country's national team of involvement in Woolmer's death.
"Nobody, at this stage, can be ruled out of the inquiry," Shields said. - Sapa-AFP
