An ambulance crew, which was called at 1 am, arrived in 5 minutes and performed resuscitation measures, including adrenaline injections, on him for half an hour however this didn't help. He died from cardiac arrest (according to preliminary data) even before an ambulance's arrival at the age 36. His death was reported on Facebook by his father Aleksandr Tolmatskiy at 6 am.
