Two police officers who tried to prevent two colleagues from robbing a post office in Greytown, Natal, were forced to open fire on the two villains.
Warning shots were fired before the two police officers were each shot dead before they could carry out the robbery.
The two on-duty police officers received a hint that a robbery would be carried out at the post office, and two members of the Falcons unit rushed there to prevent the robbery.
The police first wanted to put the rogue police vehicle out of action, but a bullet rain greeted them, and had to answer the fire.
It is suspected that the two deceased are responsible for the series of house burglaries that have plagued the town in recent months.
