Forensic investigator Paul OSullivan has filed a counter-defamation lawsuit of R10 million against KwaZulu-Natal Police Commissioner, Nhlanhla Mkhwanazi.
Mkhwanazi filed a R5 million defamation lawsuit against OSullivan last month.
In court papers before the High Court in Johannesburg, OSullivan argues that he was accused of unspecified crimes by Mkhwanazi and was labelled an agent working for someone else.
