Eight people were arrested for public violence during a service delivery protest on Marlboro Drive, Sandton, on Monday morning, Johannesburg police said.
Spokeswoman Lt-Col Katlego Mogale said they would appear in court soon.
The road was reopened by 11am, after being barricaded with rubbish and burning tyres from around 5am.
“Everything has returned to normal.”
While it was believed the disruption was a service delivery protest, she said it was not immediately clear what group was dissatisfied about. Police were monitoring the situation. - Sapa
