It was alleged the victims, who were performing guard duties at the shop on December 7, 2014, were accosted by the officers.
The suspects allegedly forced the victims into a taxi and drove off with them.
They tied them up with cables and left them in a sugarcane field before returning to the shop, police said.
It was alleged the suspects tried to break the safe in the shop but failed.
They stole five radios and cigarettes before fleeing, added police.
A case of business robbery was reported at Pongola Police Station for investigation, and on December 14, 2014, the two suspects were arrested.
The KwaZulu-Natal provincial commissioner, Lieutenant-General Mmamonnye Ngobeni, applauded Pongola Detectives and the Provincial Tracking Team for their excellent work in arresting the two accused police officers.
“We have previously stated that we will not tolerate criminals within the police, and we have clearly demonstrated that we are equipped to arrest our own members when they do wrong,” said Ngobeni.
Police said more arrests can be expected as investigations continue.
In a separate incident, two police officers and a reservist constable appeared in the Galeshewe Magistrates’ Court, Kimberley, last Wednesday on a charge of robbery.
The three police officers in uniform went to a foreign-owned tuck shop in Magoda Street, Galeshewe, and allegedly robbed it.
