Two club cricket coaches were murdered and two others seriously injured after an attack at the Laudium Club, 17kms east of Pretoria, reports ESPNcricinfo.
The South African Police Services are investigating the case.
The deceased, whose bodies were discovered at the club ground on Thursday morning, were identified as coaches Given Nkosi, 24, and Charlson Maseko, 26.
No motive has been ascertained for their murder.
KFC Mini-Cricket co-ordinator Kagiso Masubelele, 27, and Laudium Hub Head Coach and co-ordinator Obed Harvey Agbomadzie, 27 are recovering in hospital.
All four men were residents at the Laudium stadium's living quarters and all were involved in Cricket South Africa and Northerns Cricket affiliate programmes.
Both organisations expressed their condolences.
"This is devastating news for the Northerns cricket community. They have been a highly valued and integral part of our talent pipeline development programme, particularly in the Laudium community," Jacques Faul, Northerns CEO said.
"This has come as a huge shock to the entire CSA Family. These are all dedicated cricket administrators and coaches who have been making a huge difference to the communities in which they operate, providing an important source of upliftment and hope, particularly to our youth. What they have been doing goes far beyond the game of cricket," Haroon Lorgat, CSA CEO said.
