Greek authorities arrested a 37-year-old foreign national with an outstanding European arrest warrant issued by German authorities. The arrest took place at the airport of Thessaloniki, northern Greece, on Wednesday.
The man has been sentenced to 10 years imprisonment for e-mail and telephone fraud amounting to roughly 1.5 million euros.
He was convicted as the leader of a gang that defrauded large numbers of people in Germany and other countries, convincing them to invest large sums in various financial institutions by promising high returns.
These sums were then transferred to the gang members via a complex money-laundering system operating throughout Europe.
The arrestee will be led before a public prosecutor.
