"Other suspects may be linked but the investigations will lead us to other suspects. But for now, we have a serious breakthrough with those suspects we arrested in KZN, those two were the main suspects that secured the warrants of arrest," said Mthombeni.
"So we're confident that when we place this case docket before the court of law we will have done the groundwork so that the case can be processed and ultimately we see what would be the outcome in terms of the court processes" he said.
