Captain Phumelelo Dhlamini said a group of people started to gather and block roads with stones and burning tyres at 7pm last night.

During the protest, one person was injured and a municipal vehicle was damaged.

Dhlamini said the R708 between Clocolan and Marquard was also blocked with stones. A vehicle on this road was set alight by a group of people. Police urged all motorists to use alternative roads.

Dhlamini said police were monitoring the situation and that re-inforcements were on their way.

It was not immediate clear why the protest started, however residents have previously protested against a lack of water and other aspects of service delivery.

About 20 people were arrested in July for public violence and for looting foreign-owned shops in town and in the informal settlement after handing a memorandum to the Setsoto local municipality.
