Thirty-three people have been arrested after the homes of two alleged murderers were set alight in Ga-Selela village, near Mecklenburg, Limpopo police said on Friday.
Lt-Col Ronel Otto said they were arrested on Thursday night and Friday, and would appear in the Mecklenburg Magistrate's Court on Monday.
She said the owners of the homes had been arrested earlier this week, in connection with the murder of 92-year-old Klaas Thekoane.
They appeared in the Mecklenburg Magistrate's Court on Thursday and were released on R1000 bail.
The 33 people were local residents who were unhappy with the court's decision, Otto said.
She said a third house, belonging to one of the men's relatives, was set alight on Friday morning.
No one was injured in the fires.
