The arrests came after the K9 Unit pulled over a “suspicious VW caddy” with seven occupants – who all live in Nelson Mandela Bay – while driving in Johnson Road, KwaZakhele, at about 10pm on Saturday.
Port Elizabeth Hawks commander Colonel Hyron Booysen said they believed the men were going to blow up an ATM in the Soweto-on-Sea area when they were stopped.
Police explosive experts say the men had enough explosives to blow up about 10 ATMs.
Another Hawks detective said they were trying to link the suspects to other ATM bombings around the province.
Over the past two months, bombers have blown up two ATMs in the Motherwell area. In both instances, the men fled empty-handed as the explosives failed to open the safe within the machine.
The suspects are expected to appear in the Port Elizabeth Magistrate’s Court today.
