Johannesburg - A top official in the Mpumalanga safety and security department and a company director were arrested on Thursday for irregularities with a multi-million rand tender, the Hawks said.
"The official and the security company director are facing charges of fraud and corruption over a security tender to guard the department's offices," said Captain Paul Ramaloko.
The official, who had the final say about who got the tender when it was awarded in 2011, also faced a charge of contravening the Public Finance Management Act (PFMA).
Ramaloko said investigators found the company did not meet the requirements for the tender.
"It was also discovered that the company submitted false tax certificates during the application process," he said.
The company received R4m a month from the department for its security services.
"Investigations into the case continue. More arrests are expected."
The two were expected to appear soon in the Nelspruit Magistrate's Court.
