A former teacher and Media24 executive, 55-year old Willem Breytenbach, was arrested in Hartenbos near Mossel Bay this afternoon.
He had apparently just finished a session at a psychologist when he was arrested in connection with sexual assault charges.
His arrest follows a weekly podcast by Johannesburg-based copywriter, Deon Wiggett, who had accused Breytenbach of raping him in 1997 when he was 17-years-old.
He left Cape Town after Wiggett levelled the allegations against him and had been living at his elderly mother's house in Reebok near Great Brak River for the past few weeks.
Breytenbach, who has also been accused of sexually molesting several schoolboys at three schools where he taught from 1989 to 1994.
He was a teacher at Grey College,Willowmore and Langenhoven high schools in Riversdale, where he also allegedly committed acts of sexual assault against minors before joining Media24 in 1995 as an education reporter at Die Burger.
Media24 has since condemned Breytenbach's alleged actions and called on its employees to come forward with evidence and report it to the police.
Breytenbach will appear in court on Thursday.
