German environmental activist environment "Last Generation" was sentenced to 22 months in prison for his participation in blocking roads, a spokeswoman for the Berlin District Court told DPA, BTA reported.
The man, who is 65, will have to serve his sentence without parole.
He was found guilty of coercion, attempted coercion and resisting law enforcement officers.
A spokeswoman for the Berlin District Court said the accused had taped his hands to the road.
The prosecution asked for more than two years in prison, and the defense insisted on an acquittal. The reasons for the judgment have not yet been published.
The trial began in November last year, and at the start of the proceedings the accused was offered a suspended sentence of one year in prison in exchange for a confession, but the defense did not agree.
"Last Generation" said the 65-year-old intended to appeal the sentence.
Last month, another eco-activist was sentenced to one year and four months in prison for spraying the Brandenburg Gate and taking part in street blockades in Berlin.
