Fireworks Firm's Technical Director Arrested for Fatal Explosion near Moscow

The chief technical officer of a Russian fireworks company, Piro-Ross, has been detained in connection with a criminal investigation into a deadly explosion at an optical plant in Sergiyev Posad, outside Moscow. The explosion resulted in one death, 60 injuries, and 12 people missing. The Investigative Committee has opened a criminal case for violating industrial safety requirements, with potential prison sentences of three to seven years.
