Question juridique clé
Whether preventive detention remained justified because of a risk of collusion
Solution extraite
Yes. The declarations of co-accused B.________ and C.________ were central to the case, and release could lead the applicant to influence them before trial.
Motifs extraits
A concrete and plausible risk existed that the applicant would try to contact co-accused or the presumed organizer D.________ to induce retraction of incriminating statements. A prior confrontation did not remove that risk.
