Key legal question
Whether there was sufficient urgent suspicion to justify pretrial detention for arson.
Extracted holding
The criminal authorities could reasonably find urgent suspicion based on the witness statements, the defendant's own inconsistent account, and the surrounding circumstances.
Extracted reasoning
At the detention stage, only concrete indications are required; no full evidentiary assessment is made. The testimonies of the two coworkers were credible and consistent, and the defendant's statements were internally inconsistent. An alternate motive was at least plausible.
