The guards were arrested on Saturday after they allegedly beat two men to death, according to police spokesperson Major Thulani Zwane.
“It is alleged that on Saturday, at Plaza Centre in Ladysmith, the suspects assaulted two victims with sticks and stones after they accused them of robbery,” said Zwane.
“Both victims died instantly and the suspects were immediately arrested and charged with two counts of murder.”
KwaZulu-Natal Provincial Commissioner Lieutenant General Mmamonnye Ngobeni condemned the killings.
“This is not acceptable and we had good partnership with security companies but we cannot tolerate those individuals who take the law into their own hands. If anyone is suspected of being involved in any kind of criminal activities, that person must be taken to the police so that the police can investigate and charge him if there is evidence against him,” she said.
