A police sergeant was shot dead in front of his 10-year-old son in Hercules, Pretoria, Gauteng police said on Wednesday.
Captain Agnes Huma said two men attacked Sergeant Bruwer Smit and his son while they were out riding their mountain bikes in some veld near the Mabopane highway on Tuesday afternoon.
The attackers stole Smit's takkies and made off with both bicycles.
Smit died at the scene.
The boy escaped and ran to the highway, where he flagged down a passing vehicle.
Brigadier Andre Wiese, Smit's commanding officer, told Beeld newspaper that Smit was one of the best police officers he had ever worked with.
