Mahikeng - A 26-year-old policeman based at the Potchefstroom Crime Combating Unit (CCU) was arrested in connection with the shooting of a man in Khuma, Stilfontein, the Independent Complaints Directorate said on Monday.
The policeman allegedly shot Tshepo Johannes Tau, 23, on Sunday at a tavern in Khuma after an argument, ICD spokesperson Moses Dlamini said in a statement.
"The argument apparently led to the constable being assaulted by Mr Tau.
"Then the constable allegedly went home and returned with his service pistol after which he fired at Mr Tau," he said.
Tau was shot in the stomach and cheek and his 28-year-old brother was shot in the left elbow. Both were admitted to hospital. Tau died on Monday morning.
The policeman opened a case of assault with intent to inflict grievous bodily harm. A case of attempted murder opened against the policeman had been converted to a murder charge.
Earlier on Monday North West police said the policeman was at his girlfriend's house at 18:30 on Sunday when two men entered, dragged him outside and attacked him.
Brigadier Thulani Ngubane said the policeman went to report the incident at a nearby police station.
On his way home he was again attacked by a group of people.
"He allegedly used the firearm to save himself from the mob attack. He then shot at two of the attackers and went back again to Khuma police station to report the incident," Ngubane said.
The policeman is expected to appear in the Stilfontein Magistrate's Court on Wednesday.
