Limpopo police have arrested three people for public violence and arson over the six vehicles that were torched during a protest in Lephalale, they said on Wednesday.
Brigadier Hangwani Mulaudzi said the situation at Medupi power station was quiet and that police were monitoring the area.
On Tuesday, thousands of protesters torched two buses, and damaged two police vehicles and two cars in the area.
They claimed Eskom was not considering local people for positions of boilermakers and were placing only foreigners.
“Eskom has closed the station. It will only be operational for business once the issues have been sorted out,” said Mulaudzi. - Sapa
