Warrant Officer Karl Sander, a senior Hawks investigator, took a polygraph test over missing cocaine exhibits even though he was on leave at the time.

The Madlanga Commission of Inquiry heard on Tuesday that polygraph tests of KwaZulu-Natal Hawks officers regarding the R200 million cocaine theft in 2021 were thrown out after the examiner made “serious errors”.

The 541kg cocaine bricks, seized by the Hawks from a container at Durban Harbour in June 2021, were stolen from the Hawks Port Shepstone storage facility during a burglary in November 2021.

Warrant Officer Karl Sander, a senior KZN Hawks investigator, testified that he was among the officers polygraphed over the missing cocaine exhibits.

He told the commission on Monday that he underwent the test despite being on leave when the Hawks storage facility was burgled.
