On Monday a group of armed men traveling in two SUVs attacked the security vehicle transporting cash and fired shots at its tyres until the vehicle stopped.

They then held up the security officers at gunpoint and used explosives to blast open the safe before fleeing the scene with their loot. Two security officers who were injured in the heist were taken to a hospital.

The arrested suspects are expected to appear in the Polokwane Magistrate's Court on Wednesday.
