The instigators of what the government is calling "well-orchestrated economic sabotage" are allegedly former uMkhonto we Sizwe (MK) operatives, some of whom worked in the security cluster.
MK was the ANC's armed wing during movement's struggle against the apartheid government.
"There is no doubt that they know the know-how of how MK operated, and they have organised in that way," Deputy Minister of State Security Zizi Kodwa told News24.
