Dutch national Aydin Coban has been found guilty of extortion and criminal harassment in the case of Canadian school girl Amanda Todd, who killed herself after being blackmailed by him over a nude photo.

Coban was extradited to Canada in December 2000 to face the charges after a lengthy legal battle.

Amanda Todd killed herself in October 2012 shortly after posting a video online in which she used flash cards to describe how she sank into depression after being exploited.

Coban, who comes from Tilburg, was arrested later in the Netherlands. He was found to have dozens of aliases and to be blackmailing a number of girls after getting them to send him nude photographs.

In April 2017 he was jailed for nearly 11 years for the online abuse and for blackmailing 34 girls under the age of 18 – a sentence upheld on appeal at the end of 2018.

Canada, however, wanted to try Coban for threats, abuse and blackmail through its own judicial system. The agreement with the Canadian authorities at the time would allow him to serve his sentence in the Netherlands.

Todd ‘s mother Carol told CBC after the verdict the conviction on all counts as a ‘just’ decision and a relief, many years after losing her daughter.

Todd said she believes the trial has set a precedent in Canada and around the world that shows people suspected of ‘sextortion’ can be extradited to stand trial in another country.

The Canadian court has not yet said what sentence he should serve.
