A man was stabbed to death while hunting with his girlfriend at the Emarmia Dam in Johannesburg on Friday night.
SAPS Brigadier Matapello Peters said police are investigating the murder case and that the suspect is a 38-year-old man.
Peters said the deceased, 36-year-old man was fishing with his friend when an unknown man approached them.
He said an argument broke out between them when the suspect began to flash a torch in the victim and his friend's face.
"The argument then started and the deceased and his friend then started leaving after packing their fishing rods," Peters said.
"The argument went on and the suspect started beating one victim on his left jaw. He received a cut under his jaw, but managed to escape. "
The suspect then allegedly turned to the other man and stabbed him repeatedly.
"When the running victim came back, he found paramedics trying to help his friend, with the suspect still at the scene," Peters said.
The man was pronounced dead on the scene.
