The situation in the troubled area of Boiketlong in Sebokeng, south of Johannesburg remained tense on Friday morning, Gauteng police said.
Disgruntled residents took to the streets on Thursday, demanding service delivery.
The protest also led to Metrorail, a division of the Passenger Rail Agency of South Africa (Prasa), suspending its services, leaving train commuters travelling between Vereeniging and Johannesburg stranded and frustrated on Friday.
Speaking to The Citizen, police spokesperson Lieutenant Kay Makhubela said the situation was still tense.
“Residents are still protesting, but our officers are monitoring the situation.
“The road between Sebokeng and Vereeniging remain closed to traffic,” he said.
Two injuries were reported during Thursday’s protest.
