Semyon Dementiev

He was born in Ivanovo, lived in the Moscow region, and left Russia in 2022. In January 2026, he was placed on Rosfinmonitoring's list of terrorists and extremists. No later than March 2026, he was taken into custody on charges of spreading deliberately false information about the Russian Armed Forces (as suggested by the TV channel "Beware of the News", due to reposts of films by media-foreign agents) and calls for activities against the security of the Russian Federation (presumably due to calls to donate to the AFU).
