In 1934, Nikolai and Andrian Yeltsin were arrested. The cause of their arrest was dissatisfaction with working conditions and statements against the forced collection of money "to aid Austrian workers." Nikolai Yeltsin was convicted of "counter-revolutionary activity" and sentenced to three years in corrective labor camps. He served his sentence during the construction of the
Moscow–Volga Canal in the
Dmitrovlag camp system. For exemplary behavior, he was released early in 1936. According to other sources, immediately after sentencing, Nikolai Yeltsin was exiled to the city of
Berezniki in
Perm Oblast to work on the construction of a potash plant, where his brother Ivan, who had also been arrested, was later sent. During the late 1930s, he lived in Berezniki, working on the construction of the local chemical plant. == Later life ==
