Kernrechtsfrage
Whether the extension of pretrial detention was lawful despite the lack of alleged collusion risk
Extrahierter Entscheid
The detention extension was lawful because concrete indicators of collusion risk existed in a complex multi-defendant investigation involving many offences, witnesses, and possible influence on co-accused.
Extrahierte Begründung
The court held that collusion risk may be inferred from the complexity of the investigation, the seriousness of the offences, the remaining witness and confrontation evidence, and the possibility of influencing co-accused or witnesses; mere theoretical possibility is insufficient, but the concrete circumstances here justified detention.
