Johannesburg - At least one resident of the Evergreen informal settlement outside Springs was in fear of her life after voting on Wednesday.
"I'm scared for my life," said Nokuthula Dlamini, who had already voted.
"I don't know how I'm going to sleep tonight because they threatened to attack us at night."
A group of about 50 people at the informal settlement, who had earlier threatened a night attack on voters, were burning tyres on Wednesday evening. None of them seemed to be carrying weapons.
Police stood about 500m away. No arrests were made, and no one had been attacked.
Earlier a youngster, who gave his name only as Sipho, said: "We are not voting. Those who vote, we are going to find them at night."
Protesters had called on residents not to vote, citing their living conditions and demanding the release of people arrested in protests in the area earlier this week.
In the nearby Gugulethu informal settlement, a Transnet building was torched on Monday and 46 people were arrested for public violence.
Police tried to calm an early morning protest by imploring people to save it for another day and go vote.
