Rustenburg - North West premier Thandi Modise on Wednesday condemned the killing of a former NUM shop steward at Lonmin.
“We have had enough of these despicable and heinous acts and call on law enforcement agencies to intensify efforts to curb the killing spree,” she said in a statement.
Modise said the Marikana Peace Accord signed earlier this year had been completely disregarded by perpetrators of violence.
Former National Union of Mineworkers shop steward Percy Letanang died in hospital on Tuesday night.
Letanang was shot seven times when he arrived home in Segwaelane near Marikana on Sunday evening.
He was employed at Lonmin's Eastern Platinum mine, and took a voluntary severance package after Lonmin de-recognised NUM after the number of its members fell below the required threshold.
“It is clear that our repeated pleas for people involved to resort to peaceful means to deal with their problems have fallen on deaf ears.” said Modise.
She urged those on the receiving end of the violence not to be provoked to violent retaliation.
Several killings were believed to be due to rivalry between unions.
