Parents were asked to watch their children as some of them are committing crimes during the protests in Tshwane.
“We have also noted reports of children taking part in unlawful activities and wish to appeal to parents that it is their obligation to ensure that their children are protected and kept safe,” Spokesperson Siphiwe Dlamini said in a statement.
He said government was making progress in stabilising and stamping out crime in and around the city.
The violence started on Monday, five people have been killed and 150 people were arrested on charges of public violence, burglary, theft, possession of unlicensed firearms, and possession of suspected stolen proper.
The criminals appeared in court on Thursday and they were denied bail. More cases would be heard on Friday and the State would oppose bail, he said.
While most parts of Tshwane were calm, Mabopane and Soshanguve remained a hotspot.
Widespread protests erupted in Tshwane after the ANC announced Thoko Didiza as its mayoral candidate on Monday.
ANC supporters apparently wanted mayor Kgosientso Ramokgopa to stay in the job after the August 3 local government elections.
