The Western Cape High Court on Monday found former Western Cape Police Commissioner Arno Lamoer guilty of corruption, but not guilty of racketeering and money laundering.
Earlier this month, Lamoer pleaded guilty to one of the corruption charges he faced.
Lamoer, along with tow truck company owner Salim Dawjee, and former police brigadiers Darius van der Ross, Sharon Govender and her husband Kolin Govender, faced 109 charges of corruption, racketeering and money laundering involving R1.6m.
On 8 February, Lamoer made a series of admissions in court papers.
Last week, Dawjee was found guilty of fraud and corruption, Sharon Govender was acquitted of all the charges she faced, while her husband Kolin was found guilty of corruption. Van Der Ross was also found guilty of corruption.
The case was postponed to 16 April.
