Ticino's public prosecutor's office announced on Tuesday the first findings on the causes of the explosion that occurred in early September at the Ritom hydroelectric plant. The incident had killed two workers.

According to the findings, the blast was caused by black powder, an explosive mixture. The exact quantity has not yet been determined.

In the weeks following the incident, technical analyses were carried out to reconstruct the origin and sequence of events. The analyses were conducted in collaboration with the forensic institute of Zurich, which provided a preliminary report.
