Authorities in South Africa have arrested a retired teacher accused of preying on boys at two leading public schools in Scotland.
The 83-year-old, who was referred to as 'Edgar' by former SNP leader Ian Blackford but whose real name cannot be disclosed for legal reasons, will be brought before the city's Wynberg Magistrates Court later.
The 83-year-old, dubbed 'Jimmy Savile Mark II' is accused of crimes against boys at Edinburgh Academy and Fettes College in the 1970s. He denies the allegations.
BBC presenter Nicky Campbell, who attended the Academy in the 1970s, has led calls for him to be brought back to the UK to stand trial, with a court hearing due to take place later this year.
Edgar denies having molested pupils while teaching in Scotland, and also denied accusations of similar behaviour after moving to teach in a prestigious school in Cape Town.
He is currently subject to an order at the Scottish Child Abuse Inquiry preventing his identification.
But former SNP leader Blackford earlier this month used parliamentary privilege to declare his alias as 'Edgar' in the House of Commons.
In a session of Education Questions in the House of Commons on January 16, Mr. Blackford told MPs: 'All of us in this house will prioritise keeping school children safe from sexual predators and I am sure the minister will be aware of the Scottish Child Abuse enquiry detailing the horrific allegations from a number of witnesses to events at Edinburgh Academy and Fettes schools by an individual referred to as ''Edgar''.
'I have a number of constituents who have complaints against ''Edgar''. This man has admitted to inappropriate behaviour and is currently fighting extradition from South Africa where he has been publicly named.
'There is precedence (sic) in England where another alleged abuser living in South Africa whose extradition has been sought has been publicly named.
'We now know that there are dozens of boys who have come forward to the police with allegations against the man referred to as ''Edgar''. It is important that others who were abused by this man can come forward.
'It is right that his crimes against children are named – and it is also right that he is now named.'
Earlier this month Mr. Campbell, 61, alleged he witnessed 'Edgar' abusing his friend in his school's changing rooms and described his conduct as 'so ubiquitous' that all of the pupils knew what was going on.
Speaking on BBC Breakfast, Mr Campbell said: 'He could well be one of the most prolific paedophiles in British criminal history if you do the maths and look at how long he taught and how many schools he was at.'
After Campbell went public with the allegations, other former pupils of Edinburgh Academy and Fettes College stepped forward with stories of abuse.
Edinburgh Academy has since issued a public apology and says it is cooperating with police.
In a statement to the Scottish Child Abuse Inquiry, Fettes College - whose alumni include former PM Tony Blair - made a 'full and unreserved apology'.
