Attie Potgieter, his wife Wilma and their three year old daughter Willemien were found murdered on their farm on Thursday morning. The South African farmer, in his 40s, had been attacked with a panga (machete), while his wife and infant daughter were shot.
Three of the suspects were arrested on the farm, while other three were picked up in the town of Lindley, Makhele said.
Most of the suspects are in their early twenties.
The commercial farming body, Free State Agriculture has condemned the killings with Free State Agriculture chief executive, Henk Vermeulen calling it senseless murder.
Lindley is a small town situated on the banks of the Vals River in the eastern Free State which was established by an American Presbyterian missionary named Daniel Lindley, who was the first ordained minister to the Voortrekkers in Natal.
The settlement of Lindley was laid out in 1875 on the farm Brandhoek and was proclaimed a town in 1878.
