Question juridique clé
Whether the refusal of pretrial release should be set aside because the detention requirements were not met.
Solution extraite
The appeal was rejected because sufficient suspicion existed and the detention remained justified by a concrete risk of collusion; the court did not need to examine the alleged risk of reoffending.
Motifs extraits
Pretrial detention requires a legal basis, public interest, and proportionality, together with sufficient suspicion. Here, the ongoing investigation still required identifying other participants and tracing the origin of seized jewelry; release would have risked compromising these investigative acts.
