There is a hit list targeting members of the NUM at the troubled Lonmin mine, in North West, the union said on Thursday.
The man found dead on Tuesday in an open veld near the mountain where striking workers had gathered was a National Union of Mineworkers (NUM) shop steward, the union's president Frans Baleni said on Thursday.
“We know that the list consists of shop stewards and branch members at Lonmin,” he said
Ten people have been killed in violent protests at the mine in Marikana since Friday.
Baleni said three of them were NUM members, and one was a member of the United Association of SA (UASA).
Another NUM shop steward managed to escape on Tuesday. “He has now been placed in a place of safety,” he said
Baleni said his union was “never involved” in the violence, and that the law should take its course should any NUM members be found to have been involved.
He said the union had forwarded to the police the names of the people it believed were responsible for the hit list.
On Friday, thousands of rock drill operators started an illegal strike and a protest march.
Two police officers and two security guards are among those killed.
The striking workers are demanded a salary of R12 500 a month for all workers. - Sapa
