Question juridique clé
Whether the confrontation interview of 20 October 2015 and C.___'s statements were admissible.
Solution extraite
The appellant had already become a suspect; he was not properly informed of his procedural status and rights under Art. 158 StPO, so his statements were inadmissible and C.___'s statements from 18 and 20 October 2015 could not be used against him.
Motifs extraits
After police suspicion had concretized and the appellant was taken into custody, he should have been treated as an accused person. Because he was confronted without the required warning that proceedings had been opened and without indication of the offences, his own statements were unusable; the co-accused's statements were also excluded to the appellant's detriment.
