A former teacher accused of abusing pupils at boarding schools in Edinburgh has been arrested in South Africa. The 83-year-old attended a sexual offences office in Cape Town with his lawyer on Monday morning. The man, known in a BBC documentary as “Edgar”, taught at Fettes College and Edinburgh Academy in the Scottish capital in the 1960s and 1970s. Edgar is fighting the extradition on compassionate grounds arguing that he is old, unwell, and remorseful.
