Seven suspects were arrested in Prince Albert on Wednesday following a probe into allegations of fraud, theft and corruption.
A spokesperson for the Hawks Zinzi Hani says the suspects aged between 30 and 43 include four Emergency Service officials and three petrol attendants.
She says it is alleged that the group of EMS personnel, worked hand in hand with the petrol attendants to defraud the State by utilizing petrol cards on fictitious transactions.
Hani said it is further suspected that the suspects would wait for motorists who pay in cash and would then swipe the amount on the State card before they all split the money.
The suspects are expected to appear in the LeeuGamka Magistrates Court on Thursday.
