Kernrechtsfrage
Whether continued pretrial detention was lawful despite the appellant's request for release with substitute measures.
Extrahierter Entscheid
Yes. The detention was compatible with personal liberty because there were sufficient suspicions and a concrete, serious risk of flight.
Extrahierte Begründung
The offences were serious and exposed the appellant to a substantial prison sentence. His foreign ties, limited integration in Switzerland, intent to return to the Dominican Republic, and links remaining abroad made flight likely.
