This happened in Estonia as well. Communists attempted to overthrow the Estonian government in a coup in 1924, a couple of those involved were executed, many were imprisoned in the Patarei Prison in Tallinn (later gained notoriety under Soviet occupation for holding political prisoners), and some fled to the USSR. Ironically, those who were imprisoned fared slightly better than those who fled to the USSR, since many of the latter were purged by Stalin, while the former were given amnesty in '38, on the 20th anniversary of the founding of Estonia.

The new Stalin book by Kotkin goes into this episode. A totally crazy coup Stalin basically cooked up with some people and he didn't even inform the Politburo.
