Irate informal settlement residents have clashed with police, barricaded streets and set municipal buildings alight.
They also upended rubbish bins in a bid to prevent police from entering parts of Diepsloot, north of Johannesburg, on Monday.
The angry residents believed they were about to be forced to move to Brits, west of Pretoria, in North West province.
Tempers flared after the area councillor, Sarafina Mulaudzi, allegedly told a public meeting last week of the plan to relocate residents in informal dwellings on July 14.
Furious, the residents gathered outside Mulaudzi's house on Monday and demanded answers from her.
Toyi-toying and chanting slogans, they shouted: "Phansi ngo Sarafina, Asimufumi" meaning "Down with Sarafina, we don't want her!"
Heated arguments erupted between police and the residents, who took to throwing stones at the police.
A metro police officer was taken to Milpark Hospital in
Johannesburg after being struck by a stone.
Metro police Chief Superintendent Wayne Minnaar later said the officer received injuries to a hand and was in a stable condition.
Police eventually dispersed the protesters, using rubber bullets.
Pretoria police Inspector Percy Morokane said 11 people were arrested for public violence, and police would monitor the area to make sure there was no further violence.
One resident, Thabo Shabalala, said they had been removed to Diepsloot from Alexandra in 2000, after flooding along the Jukskei River threatened informal settlements.
"We are tired of empty promises. We were promised RDP houses but we still live in the shacks. How can we move from shack to shack?
"We refuse to go there (to Brits). We will remain here, whether they like it or not. We will die here," Shabalala said.
"Brits is far away from our workplaces. How do they expect us to go to work?
"We will spend R50 a day just for transport. How are we going to survive if we have to spend so much?
"This is annoying - these people are not delivering. Is this what we voted for?" Shabalala asked.
An irate Zinhle Khumalo said it would be difficult for her children to attend school.
"Sarafina should have spoken with the residents first, before making such a decision. We don't have material to erect new shacks.
"After they moved us from Alexandra, we made Diepsloot our home," Khumalo said.
Mulaudzi could not be reached for comment on Monday, but City of Johannesburg spokesperson Nthatisi Modingoane denied there were plans to remove residents to Brits - and Mulaudzi had, in fact, told residents last week she knew nothing about such a decision.
Modingoane said the council condemned violence because the city had always stated people had the right to talk to their leaders about issues they felt needed to be addressed.
