Johannesburg - Forensic investigator Paul O'Sullivan's assistant has been arrested, AfriForum said on Friday evening. AfriForum's lawyer Willie Spies said Sarah Jane Trent was arrested earlier on Friday afternoon on charges of statutory offence. Spies said Trent was taken by police and driven around in the back of a police van for hours before being taken to Cullinan police station. "Clear police are harassing and intimidating Trent."Spies said Trent was charged for her involvement in an IPID investigation of acting police commissioner Lieutenant General Khomotso Phahlane. He said AfriForum lawyers were currently at the Cullinan police station in an effort to have her released. "It shows that they wanted to intimidate her. For them to choose to arrest her on Friday and drive around with her for the sole reason of keeping her for the weekend shows intimidation."Spies said AfriForum was considering taking the matter to the High Court.Earlier on Friday, O'Sullivan told News24 that police raided his home in Johannesburg.He said the doorbell rang at his house in Sandton at 16:15. He said when he opened it, there was a female metro police officer who asked to be let in.O’Sullivan said the woman said she needed information on his vehicle, which was apparently involved in a hit and run two weeks ago. He said he told her he sold it about a year ago.O’Sullivan said he had a bad feeling about the situation, got into his car and drove away. He said as he left, he saw a convoy of unmarked vehicles coming toward his house.He said the cars tried to block him off but he drove away.Phahlane is seeking to interdict O’Sullivan from being involved in IPID investigations against him, News24 reported. The papers were on Monday served on the Independent Police Investigative Directorate (IPID), O’Sullivan, Sarah Trent, and Magistrate JR Tsatsi.Phahlane says O’Sullivan has been targeting him and has the ear of IPID head Robert McBride.
