Victor Kaliadin

Victor Kaliadin, (Виктор Калядин, born: 1949; died: September 16, 2004) - was a CEO of a Russian company "Elers Electron" (Элерс электрон). In 2001 he was sentenced to 14 years in prison by a Russian court for allegedly selling a ring run by a Defense Intelligence Agency (DIA) agent technical information on Arena, the Russian active protection system for tanks.

Death
Due to Kaliadin's rapidly deteriorating health, three years into his sentence he was temporarily transferred to the city hospital of Lipetsk, where he died of his fourth heart attack in 2004. His wife Ludmila said that she intended to sue the Russian government for refusing to conduct appropriate medical screenings for her husband, who she claimed was eligible for release due to his health conditions.
