The three were arrested in Mokopane in July after violence erupted during a community meeting, Captain Sebotsaro Motadi said.
Mogalakwena mayor Tlhalefi Mashamaite failed to arrive as promised to address Mzombane residents on service delivery problems, Motadi said.
A councillor then took the microphone.
“As he was trying to address them, a group disrupted the meeting. The three suspects stoned the councillor’s car… They later identified themselves as Agang SA members,” Motadi said.
The three men would appear in court on Friday.
