Twenty-seven people arrested during a protest appeared in the Barberton Magistrate's Court on Friday, Mpumalanga police said.
They were arrested earlier in the day and were charged with public violence, said Sergeant Gerald Sedibe.
He said three of them were released on bail of R750, and the rest on warnings. Eighteen other people arrested were released earlier, after police discovered they were minors.
The protesters barricaded roads with stones and burning tyres. Police used teargas on them when they looted shops belonging to foreigners.
They were demanding that the proposed Mpumalanga University, which was rumoured to be built in White River, instead be constructed in Barberton.
They believed that this would alleviate unemployment in the area. - Sapa
