Pretoria, Gauteng – In a chilling development that has raised serious questions about the integrity of South Africa's military, the investigation into the daring heist at the Tek Base ammunition depot in Pretoria has pointed squarely toward an "inside job." Investigators now believe that the thieves who made off with high-calibre weaponry, including R4 assault rifles and a grenade launcher, did not need to force their way in—they likely had the keys.
The robbery, which was discovered on Monday, 27 April 2026, occurred at the South African National Defence Force (SANDF) Tek Base in Lyttelton. While initial reports suggested a sophisticated external raid, the latest findings from military police and the Hawks indicate a far more disturbing reality: the culprits were likely those entrusted with the base's security.
'They Knew Where to Look': The Key to the Safe
Sources close to the investigation have revealed that there was no sign of forced entry into the high-security safes where the ammunition and weapons were stored. Instead, it appears the thieves knew exactly where the keys were kept and how to bypass the electronic security measures designed to protect the depot.
"This was not a random act of burglary," says a senior military expert. "To get into that depot, you need specific knowledge of the layout, the guard rotations, and most importantly, the location of the keys. The fact that they walked in and out with heavy weaponry without triggering an immediate alarm suggests they had help from the inside."
The theft was only discovered when an SANDF member returned from an official funeral and noticed the discrepancy. By then, the thieves had vanished, along with several R4 rifles and a grenade launcher—weaponry capable of causing immense destruction in the hands of organised crime syndicates.
A History of Betrayal at Tek Base
For many in the defence force, this latest incident feels like a case of history repeating itself. In December 2019, Tek Base was hit by a similar heist where 18 R4 rifles and three 9mm pistols were stolen. That investigation also concluded that it was an inside job, leading to the arrest of several SANDF members.
The fact that the same base has been breached again in such a similar manner has led to calls for a total overhaul of military security protocols. Military analysts argue that the recurring thefts are proof of a "defence force in free fall," where internal corruption has become as great a threat as any external enemy.
"We are seeing a systemic failure of discipline and oversight," says an analyst from a Pretoria-based security think tank. "When the people meant to guard the weapons are the ones selling them to the highest bidder, you no longer have a defence force—you have a supermarket for criminals."
The Hawks Move In: Arrests and Allegations
The Hawks, South Africa's elite crime-fighting unit, have taken over the investigation and are currently questioning several SANDF members who were on duty at the time of the theft. While no official charges have been announced yet, sources indicate that a "web of collusion" has been uncovered involving guards and sentries who allegedly looked the other way while the robbery took place.
In some instances, it is alleged that grinders were used to breach secondary safes, but the primary access was gained through the use of official keys. The investigation is also looking into whether the stolen weapons have already been moved out of the province or even across the border.
The SANDF leadership has remained relatively tight-lipped, only confirming that a "major security breach" is under investigation. However, the pressure is mounting on the Ministry of Defence to provide answers as to how such a high-profile facility could be so easily compromised.
National Security at Risk
The implications of this theft go far beyond the loss of military property. The R4 assault rifle is the standard-issue weapon of the South African military and is highly sought after by cash-in-transit heist gangs and other violent syndicates. The addition of a grenade launcher to the criminal arsenal is a terrifying prospect for law enforcement.
"These are not weapons for self-defence; they are weapons of war," says a spokesperson for a national police union. "When these guns hit the streets, it is our members and the public who pay the price. The SANDF needs to take responsibility for the fact that their internal failures are directly contributing to the violent crime crisis in this country."
As the investigation continues, the focus remains on identifying the "enemy within." For the residents of Pretoria and the broader South African public, the hope is that the Hawks can recover the weapons before they are used to claim more lives. But the deeper question remains: how many more keys are in the wrong hands?
