Kernrechtsfrage
Whether security detention was justified by a concrete risk of flight.
Extrahierter Entscheid
Yes. The combination of foreign ties, prior residence abroad, serious sentence, and personal circumstances made flight sufficiently probable.
Extrahierte Begründung
Risk of flight is assessed by the totality of circumstances. The imminent multi-year custodial sentence made absconding more concrete, despite the applicant's Swiss ties and prior liberty.
