Former policeman Gerhardus du Plessis, the man involved in the killing of Chanelle Henning, pleaded guilty to corruption charges in the Pretoria Specialised Commercial Crimes Court on Tuesday.

Magistrate Dawie Jacobs sentenced Du Plessis to 15 years in prison, which would run concurrently with the 18 years he is currently serving for the Henning murder.

The corruption charges are unrelated to the Henning case.

Du Plessis was put on medical leave in May last year because of post traumatic stress disorder after attending to a scene where an infant was murdered.

In August last, year he was approached by one Frederick Olivier to obtain a murder docket in exchange for R10 000.

Du Plessis took the docket from the office of investigating officer Stephanus Kilian after getting the key under false pretences. In August, he handed the docket to Olivier in exchange for a number of payments which amounted to R10 000.

The State suggested the sentence of 15 years because of mitigating factors, including the fact that Du Plessis had three young children and his wife was unemployed.

His family was also homeless as they had to move out of police barracks.
