A criminal case is most likely not going to be opened over the firecracker explosion. This was reported to ITAR-TASS (a Russian state news agency) by the Moscow police department. They specified that the firecrackers had been tied to a lamppost near the entrance to the shopping center. The blast shattered windows and tore several letters off the shopping center’s facade. All shoppers and staff were evacuated from the complex after the explosion. What kind of firecrackers are these, if they can rip letters off signs?
