A man has been killed by a bombardment of oranges thrown at him during an argument on a farm.

Two men have been arrested over the death of a farmworker in a rural part of South Africa.

According to witnesses, the victim and the suspected attackers had a row and they began pelting him with loose fruit.

Police investigating the incident said the man had no obvious injuries, raising the possibility he was killed by a blunt force trauma.

Police lieutenant Colonel Moatshe Ngoepe called it a "complicated" case. "They started pelting the deceased with all those loose oranges, killing him on the spot.

"The paramedics found that the man was dead when they arrived on the scene. He had been hit very badly by oranges," he said.

Two men aged 27 and 30 are being held by police over the incident, which happened on a farm near the town of Tzaneen in Limpopo province.
