Yes. Lapua movement was a far right anticommunist terror group that was heavily inspired by the german nazis. They are known for kidnapping suspected leftists and driving them far away and leaving them there without their belongings or outright murdering them. Once they even captured a previous finnish president that was too leftist for their taste. And they were also allowed to capture leftist parliament members in the middle of a meeting without any opposition from police.

The Finnish military, police and government were all controlled by far right at that time. Lapua movement acted as a terror wing while the coalition party acted as the "legitimate" political wing.

The current day political situation in finland is moving into scarily similar direction with the same coalition party leading government and basic finns party that has numerous barely hidden connections to different neonazi groups.
