Bricks were thrown and a branch member was shot during a general meeting of a Limpopo ANC branch on Saturday.
The incident took place apparently because there were differing opinions on who should be nominated as treasurer after the position was left vacant by the late Education MEC Thembi Nwendamutswu.
Branch member Bigboy Nkuna was shot and injured during a struggle with another member.
Police said the fight happened at Relela in Mapani.
It was alleged that the victim was chasing the armed man before he was shot in the stomach.
Police spokesperson Colonel Ronel Otto confirmed a case had been opened, but said no one had been arrested.
Otto said a group of angry ANC members retaliated by torching the house and car of the suspected gunman.
