A Soweto woman suspected of being behind explosives used in ATM bombings has been arrested.
Police have also arrested four men. They and the woman will appear in court this week.
The five are said to be linked to the recent spate of ATM bombings across Gauteng and Mpumalanga.
Police spokesman Inspector Sankie Tsunke said the 51-year-old woman was arrested on suspicion of selling explosives to the suspects.
Tsunke also said the men were linked to a series of ATM bombings in Gauteng and other provinces.
"We have been working on this for a long time," Tsunke said.
"The four men are linked to an ATM bombing that took place at the weekend in Kanyamazane, Mpumalanga."
The suspects were found in possession of 13 commercial explosives, blasting caps and three detonators.
Police also recovered an AK-47 automatic rifle, a shotgun and an unlicensed 9mm pistol and live rounds of ammunition from the suspects.
"They are all in police custody and will face charges of contravening the Explosives Act 26 of 1956 as well as of being in possession of an unlicensed firearm and ammunition.
"Investigations are still continuing," Tsunke said.
Meanwhile, ATM machines across the country will be off line on Sunday August 10.
This because Telkom will be doing a routine maintenance and updating of the VSAT (Very Small Aperture Terminal) Internet access service.
The machines will be off-line between 1am and 6am.
But not all machines will be affected on that day, according to the four big banks.
