The man, arrested on Thursday, was wanted internationally for alleged cryptocurrency fraud. According to the newspaper "Républicain Lorrain", the man in question is Frank Schneider, a former employee of Luxembourg's secret service "Srel".
Schneider played a key role in the so-called "Srel case", which led to the resignation of former Prime Minister Jean-Claude Juncker in 2013. The case involved claims that Juncker had failed to stop illegal security agency activity, including phone taps and corruption.

Schneider's name was allegedly mentioned multiple times during the OneCoin fraud trial in New York in 2019. OneCoin was a cryptocurrency firm which operated as a Ponzi scheme. The founder of OneCoin disappeared in 2017, after the firm had already raised four billion US dollars.
During the Srel trial in 2020, Schneider was acquitted in the context of the illegal bugging of electronics specialist Loris Mariotto in 2007.
