An inquest into the suspected self-inflicted death of a Russian-born gun and Nazi “fanatic” who “supported the actions” of mosque terrorist Brenton Tarrant is underway in Christchurch.

Artemiy Vldimirovich Dubovskiy, known as Troy, died after a stand-off with armed police at a suburban Christchurch park in March 2019, just 12 days after the terror attack that left 51 worshippers dead at two city mosques.

The day before, police had raided the 54-year-old’s St Martins home after a tip-off from a member of the public.

Officers found a cache of firearms, including a modified semi-automatic weapon, ammunition and “violent extremist content”, along with Nazi uniforms, helmets and clothing.

Dubovskiy, who had spent time in jail for a violent home invasion where he put a replica German World War II Luger pistol to a man’s head, did not return to his home after work the day it was raided by police
