Schneider is suspected of being implicated in the OneCoin cryptocurrency scandal and previously admitted to working with so-called crypto queen Ruja Ignatova.

Ignatova in June 2022 was added to the FBI’s after being charged in absentia for wire and securities fraud and money laundering for her OneCoin scheme. She faces up to 90 years in prison.

Schneider was arrested in France in 2021 and fought several appeals against extradition to the US. A confirmed the decision by a to send Schneider to the US. France’s prime minister, Elisabeth Borne, finally signed the extradition order.

Schneider is now facing an arrest order, the public prosecutor’s office in Nancy confirmed to Radio 100,7 in Luxembourg, after going missing. He had been placed under house arrest with an electronic ankle tag.

Court documents by the Southern District of New York’s office said that OneCoin was built with the intention to defraud investors. “OneCoins were entirely worthless,” US attorney Damian Williams said, with the cryptocurrency sold through a global multi-level marketing network. “Victims invested over four billion dollars worldwide in the fraudulent cryptocurrency.”

Co-founder Karl Sebastian Greenwood in December last year pleaded guilty to charges of wire fraud and money laundering. Greenwood was arrested in Koh Samui, Thailand, in July 2018 and extradited later that year.

Schneider is referred to as a co-conspirator by the US attorney’s office.

The former secret service agent in 2020 was of charges of illegal wiretapping in a case dating back to his time in office in 2007. Marco Mille--the head of the Luxembourg secret service (Srel) at the time--and fellow agent André Kemmer, were also exonerated.
