Ukrainian businessman Dmytro Firtash, who was released on Thursday by a court on a bail of EUR125 million and a promise to remain in Austria as part of a case over his extradition to Spain, was immediately re-arrested as part of a case over his extradition to the United States, according to Austrian media reports, which were confirmed by the businessman's lawyers.

The court is to decide on a measure of restraint for Firtash in the "American" case on Friday, February 24.
