Key Takeaways
- Two improvised explosive devices (IEDs) were detonated at Woolworths Menlyn Park (Pretoria) and Preller Square (Bloemfontein) stores in the early‑morning hours of 28‑29 May 2026.
- No injuries were reported, but an explosives expert warned the devices were “possibly lethal” due to shrapnel that could have caused serious harm or death.
- The timing, small size, and closed‑store detonation suggest the blasts were intended to send a message rather than cause mass casualties.
- Expert Willem Els (former SAPS explosives investigator, now with the Institute for Security Studies) assesses the incidents as hallmarks of an extortion campaign similar to past bomb‑related rackets in KwaZulu‑Natal.

Incident Overview
On the night of 28 May 2026, an improvised explosive device detonated inside the Woolworths Menlyn Park store in Pretoria between 01:00 and 02:00, while the premises were closed. Less than 24 hours later, a second device exploded at the Woolworths Preller Square branch in Bloemfontein during the same early‑morning window. Woolworths confirmed that no staff or customers were present at the time of either blast, and consequently no injuries were reported. The Menlyn Park outlet has since resumed operations, whereas the Preller Square location remains shut as investigators continue their work.
Expert Assessment of Lethality
Willem Els, a former SAPS explosives investigator turned consultant with the Institute for Security Studies’ transnational threats and organised crime programme, examined images supplied from the scenes. He noted the presence of shrapnel that had pierced store shelves, emphasizing that if such fragments had struck a person nearby, the outcome could have been fatal or cause serious injury. Els stressed that “a bomb is a bomb. It will always be dangerous even if no one was hurt,” labeling the devices as “possibly lethal” despite the fortunate lack of casualties.
Indicators of a Message‑Blast Rather Than Mass‑Casualty Attack
Els highlighted that the devices were relatively small in size and detonated during hours when the stores were empty, suggesting the perpetrators aimed to avoid harming individuals. The early‑morning timing, combined with the limited explosive yield, points to an intention to send a warning or demonstrate capability rather than to maximize loss of life. This pattern aligns with tactics used in extortion schemes where the threat of violence is leveraged to coerce compliance.
Link to Extortion Tactics
Based on the evidence, Els assessed that the attacks bear the hallmarks of an extortion campaign targeting Woolworths outlets. He drew parallels to previous incidents in Durban, where extortion rackets employed explosive devices to pressure businesses into paying ransoms, threatening further bombings if demands were not met. The expert warned that perpetrators often seek to erode public trust in a brand and jeopardize customer safety, counting on the retailer’s desire to protect its reputation and workforce to concede to their demands.
Historical Context of Similar Attacks in South Africa
Els referenced a history of bomb‑related extortion in KwaZulu‑Natal, noting that a few years ago Durban experienced a wave of attacks where criminal groups used improvised explosives to intimidate businesses. The Woolworths devices resemble those earlier bombs in construction and deployment, reinforcing the hypothesis that a similar extortion motive may be at play. Such historical precedents help investigators narrow down potential suspect profiles and modus operandi.
Impact on Public Trust and Business Operations
The expert explained that even without physical harm, bombings damage a retailer’s standing by shaking consumer confidence and raising fears about store safety. This erosion of trust can lead to reduced foot traffic, financial losses, and long‑term brand harm—exactly the leverage extortionists seek. Woolworths’ response, therefore, must address both the immediate security threat and the broader reputational risk to prevent the attackers from achieving their strategic goal.
Woolworths’ Official Response
In a statement, Woolworths confirmed that the two incidents were separate and that both stores were closed when the devices exploded between 01:00 and 02:00. The retailer emphasized that no one was harmed, noted that SAPS was notified immediately, a thorough sweep was conducted to rule out additional threats, and the Hawks were appointed to lead the investigation. While details about the devices’ composition or the attackers’ motive remain pending, Woolworths said it has heightened vigilance nationwide and engaged specialist forensic experts to fortify its security and intelligence capabilities. The Menlyn Park store has reopened; the Preller Square outlet stays closed pending further investigative steps.
Leadership Commitment to Safety
Incoming Woolworths Group CEO Sam Ngumeni reiterated the company’s dedication to protecting employees and customers, describing Woolworths as a proudly South African brand built on integrity and the courage to do the right thing. Ngumeni pledged that the company is taking every possible action to safeguard its people, underscoring that staff and customer welfare remain the top priority amid the ongoing investigation.
Ongoing Police Investigation
The Hawks’ Serious Organised Crime Investigation unit in Bloemfontein confirmed they are probing an alleged explosion at a clothing store in Preller Square. According to their report, the store manager received a call from a security firm at approximately 03:00 on 29 May 2026 alerting him to the blast. SAPS Explosives Unit and other relevant stakeholders are on the scene, and investigations into the cause and origin of the explosion continue. No further information on the nature of the devices or the motive has been released at this stage.
Union Reaction and Stance
The South African Commercial, Catering and Allied Workers Union (SACCAWU), which represents many Woolworths employees, expressed shock at the bombings and condemned the attacks. SACCAWU’s Sithembile Tshwete stated that the union does not support such acts and hopes all members remained safe. She emphasized that member and customer safety is paramount, urging SAPS to pursue the perpetrators relentlessly. Tshwete also clarified that the union is unaware of any labour dispute or grievance linking its members to the incidents, noting a long‑standing cordial negotiating relationship with Woolworths and no recent conflicts that could have motivated the bombings.
Conclusion and Outlook
The explosions at Woolworths Menlyn Park and Preller Square, while fortunately causing no injuries, have raised serious concerns about the potential lethality of improvised explosive devices and the possibility of an extortion‑driven campaign. Expert analysis points to a deliberate attempt to send a message through low‑yield, early‑morning blasts that could have inflicted severe harm had anyone been present. Woolworths’ swift security enhancements, cooperation with SAPS and the Hawks, and public reassurance from leadership aim to mitigate immediate risks and restore confidence. Meanwhile, the ongoing investigation by the Hawks’ organised crime unit will be crucial in uncovering the perpetrators’ identity, motive, and any broader criminal network involved. Until those details emerge, retailers and authorities nationwide remain on heightened alert, mindful that even non‑fatal bombings can exert substantial pressure on businesses and communities alike.
