Major Thulani Zwane said the man, 26, had broken into a house and shot a man, 24, and his child at about 11.30pm on Sunday. A woman escaped unharmed.
“Police were called to attend the scene and on their arrival they found AK47 rifle cartridges, and a double murder case was opened for further investigation,” Zwane said.
The man was arrested soon after the murder and would appear in the Ndwedwe Magistrate’s Court on Tuesday.
The motive for the killing was unknown.
