Questão jurídica principal
Whether preventive detention could be maintained because of a concrete risk of collusion.
Decisão extraída
Yes. The authorities could rely on specific circumstances showing a plausible and concrete risk that the appellant would influence witnesses, conceal evidence, or otherwise impede the investigation.
Fundamentação extraída
The record contained a witness statement that the appellant had asked for a false deposition, later partial admissions by the appellant, contradictory statements, unanswered questions, and a large body of seized accounting documents still to be examined. The destination of allegedly diverted funds remained unclear, making further investigative steps foreseeable.
