Gauteng police are investigating the murder of seven men, whose bodies were found dumped in a veld near a mine shaft in Benoni on the East Rand.
The bodies were discovered on Sunday morning.
Police say preliminary investigations suggest the group may have been killed days ago.
Police spokesperson Lungelo Dlamini says the identities of the victims are not yet known.
He has appealed for anyone with information to please come forward.
“When we arrived there we found that all those bodies had bullet wounds and they were dumped there. It appears as if they were killed somewhere and dumped in the area. All of them they were men, we suspect that they are illegal miners,” adds Dlamini.
