Kernrechtsfrage
Whether detention could be maintained or extended on the ground of collusion risk under Art. 52(1)(b) VStrR
Extrahierter Entscheid
The record did not show concrete indications that A. could influence witnesses, co-suspects, or evidence after release; the collusion risk was properly denied.
Extrahierte Begründung
Several co-suspects were already detained and questioned, other suspects were abroad or not yet identifiable, and the remaining possibility of new findings from IT evidence was too abstract. Since A. had known of the investigation for months, the authority had to show specific post-release obstruction risks, which it did not.
