Overview
- The Berlin public prosecutor formally discontinued the three-year investigation into the 2022 fire and detonations at the Grunewald police explosive-disposal site, citing a lack of provable misconduct.
- Experts conclude that an autocatalytic decomposition of stored nitrocellulose most plausibly triggered the blaze and subsequent detonations, though the exact mechanism remains uncertain.
- Firefighters deployed robots, helicopters and an armored vehicle to contain the inferno after illegal fireworks and World War II munitions ignited on August 4, 2022.
- Investigators early on ruled out intentional arson and found no evidence of criminal negligence or faulty storage practices contributing to the incident.
- The disposal facility has since reopened under a revised operational concept that significantly reduces the quantity of seized explosives and enhances safety measures.
