Efimov confessed his intention to carry out an attack with explosives against the aforementioned cathedral on Sunday, for which he prepared an explosive. The prosecution ordered the preventive detention of the suspect until next February 13.
During the interrogations, the arrested man was repentant and willing to offer information about his accomplices and indicated that his actions were influenced by other people.
Efimov leased a metal container in Litovski Street 8A and in the chemical store, whose strong smell caught the owner's attention, who opened it with a duplicate and found there a white powder, which later turned out to be explosive, knobs of acetone and plastic gloves.
The next day, the owner of the container observed by a closed-circuit camera how Efimov left there materials in several construction bags. In one of them, the owner of the container found a coffee can full of nails and explosive substance.
In general, terrorists stuff their homemade bombs with screws, small sheets of metal, pellets or nails to increase their deadly effect.
