Attempts to set fire to Khrustalny, where Tutberidze's group trains, were made in Moscow
An unknown person poured a flammable liquid into a crack near the window of the sports complex. But he failed to set the building on fire the first time. The man left and returned with a new bottle.
The intruder still made it to the end - smoke came out of the building, but security responded in time and extinguished the fire. Fortunately, no one was hurt.
