The available evidence provided sufficiently concrete indications that the appellant may have participated in unfaithful management.
Motifs extraits
The court held that, at the detention stage, concrete suspicion is enough; the alleged price manipulation, coordinated conduct, and statements of co-accused made the participation plausible, while the exact extent of damage remained for the criminal investigation.
