A unit commander of the Durban organised crime, Colonel Gavin Jacob, has denied any involvement in the 2021 drug theft in KZN.

Colonel Gavin Jacob has conceded that the polygraph test he once used to support his innocence in a R200 million cocaine theft probe may be unreliable after similar tests were found to contain errors.

Jacob made the admission while testifying before the Madlanga Commission on Wednesday, where he firmly denied any involvement in the disappearance of 541kg of cocaine from a Hawks storage facility in Port Shepstone in 2021.

Jacob told the commission he had no knowledge of security shortcomings at the facility and had never participated in the theft.

“I must add that I bore no knowledge, nor am I involved in the theft of the drugs. I was questioned and polygraphed about this incident. I passed the polygraph test,” Jacob testified.
