Mandeni protesters torched three factories and a car during the night protest on Thursday.
Police had to use stun grenades to disperse the community members who allegedly became violent after handing over a memorandum to the municipality.
The protests continue since Monday.
According to the police spokesperson Lt-Col Thulani Zwane, officers were monitoring the situation.
“They went to nearby shops where they looted and vandalised those shops. One suspect (27) was arrested for public violence at Mandeni police station.”
He also stated that in the morning the roads were still blocked with rubble and stones.
“No arrests have been made for the burning of factories,” Zwane confirmed.
