The Toompea Subdistrict of the Defense League's Tallinn District described 32-year-old Mikk, a former Defense League member who has been detained after shooting two people in Lihula at the weekend, as a man who was easily irritated and aggressive.
The squadron said in a statement on Monday: "He was an active Young Eagle as a boy. After he became the leader of the Young Eagles, it turned out that he was an easily irritated and aggressive man, whose language was also inappropriate for the Defense Alliance. Let us be clear: very quickly he was no longer considered suitable for his position."
Removing Mikk from this post was not an easy task as he used various legal loopholes to stop the process.
"Finally, seven years ago, a compromise was reached which he would write his own resignation to avoid being thrown out or fired. His application was granted immediately," the statement said.
The motorcyclist, named as Virgot, who chased Mikk after he killed two people on Saturday, was also a member of the Toompea Subdistrict of the Defense League.
"By his behavior that night, he embodied what a Defense League member should be: Attentive to his community and daring to stop the offense," the Defense League said.
Virgot only joined the league earlier this year. The Defense League will lay a wreath of his grave.
The commander of the Toompea Subdistrict, Ilmar Raag, expressed his condolences to Virgot's family and relatives on behalf of the subdistrict.
