Woolworths says it has increased vigilance across its stores nationwide following explosions at two branches over the past two days.

In the early hours of Thursday morning, an “unknown explosive device” detonated on one of the store shelves at the Menlyn Park Mall branch in Pretoria, while a second explosion was reported in Bloemfontein at the Preller Square branch on Friday morning.

Incoming CEO Sam Ngumeni says specialist forensic teams have been contracted to strengthen security and intelligence measures as a precaution.

“Woolworths is relieved to share that no one was harmed in either incident. In both instances, the devices were set off between 01:00 and 02:00, when stores were closed. Some staff members have, understandably, been affected by the events, and Woolworths is providing all of the necessary support to our teams.”

Ngumeni confirmed that the Menlyn Park store in Pretoria has reopened following yesterday’s explosion, while the Preller Square branch in Bloemfontein remains closed as investigations continue.

“On both occasions, the South African Police Service (SAPS) was informed immediately, a thorough sweep was done of the areas to ensure no further threats were present, and the Hawks were appointed to investigate. Woolworths has extended its full cooperation to authorities and will continue to work closely with them as the investigation unfolds. At this stage, no further information on the nature of the devices or the motive behind these attacks is available.”

The retailer maintains that the safety of its staff and customers remains its main priority.

“An attack on our business is an attack on our values, and the millions of people we serve. Our business has thrived for nearly a century because our people make the decision each day to show up and excel. That won’t change. Our doors will stay open, and our values will continue to be evident in every experience, and every product, as they have always done,” Ngumeni added.
