The Zondo commission heard last week that a senior police officer had informed the investigators about new threats to Agrizzi’s life.
Agrizzi also told the commission that he had in the past found a message on the window of his car, saying he should stop talking.
Agrizzi has implicated senior government officials in having received bribes from Bosasa after they assisted his former company to secure lucrative tenders from national and provincial governments. He also claimed that the ANC top six leaders received donations of between R10million and R12m from the facilities management company.
On Sunday, Cope leader Dennis Bloem said the country needed more people like Agrizzi to appear before the inquiry, led by Deputy Chief Justice Raymond Zondo.
