A husband and wife are among eight suspects in police custody for their alleged involvement in a diamond investment scam of R4 billion.
Police Spokesperson Colonel Philani Nkwalase said on Tuesday a multi-disciplinary operation led by the Hawks in the Northern Cape rounded up the suspects in Gauteng and the North West respectively.
He says it is believed that the husband and wife are the masterminds behind the scam.
Colonel Nkwalase said, diamond investors had been scammed since 2019 losing billions.
He says more arrests are imminent.
The eight suspects are expected to appear in the Bronkhorstspruit Magistrates Court on Thursday to face charges of fraud, money laundering, theft and racketeering.
More charges could be added at a later stage.
