Zandspruit residents protesting over poor service delivery.
The Johannesburg metro police say violent protests in Protea Glen in Soweto have resumed.
Residents began protesting at around 3am, said Chief Superintendent Wayne Minnaar.
"They are burning tyres and throwing stones," he said.
Traffic was being diverted off the Chris Hani road.
"[The road] is closed to traffic between Ndaba Drive and the N12. Motorists are advised to use Impala Road or go through Dobsonville and Diepkloof to go through and into Soweto as the Protea South area is not safe," said Minnaar.
Locals began protesting in the area on Thursday, demanding better service delivery.
Nineteen people were arrested for public violence on Thursday after they allegedly threw stones at the police. – Sapa
