Johannesburg — The situation in Sasolburg was quiet on Friday morning after almost a week of protests, Free State police said.
Colonel Motantsi Makhele said that although the area appeared quiet, authorities would continue to monitor the situation.
Four people have been killed since protests over municipal demarcation began on Sunday.
Residents were unhappy about the proposed merger, in 2016, of the Matsimaholo municipality in Sasolburg with the Ngwathe municipality, under which Parys falls.
Co-operative Governance and Public Affairs Minister Richard Baloyi announced on Tuesday that the merger would not immediately go ahead.
On Thursday, Independent Police Investigative Directorate (Ipid) spokesman Moses Dlamini said that the police's involvement in two of the deaths would be investigated.
The Ipid would also probe two cases of attempted murder.
Makhele said at the time that the police were awaiting post mortem reports and trying to determine whether the deaths were protest-related or criminal acts.
