Venezuelan opposition leader Leopold Lopez has been sentenced to 13 years and nine months in prison for inciting violence.
Leopold Lopez, 44, was found guilty of inciting violence during protests in 2014, which killed 43 people on both sides of the political divide.
Since February 2014, he has been in a military prison.
While waiting for the verdict, a fight broke out between supporters and pro-government activists near the court building in Caracas.
Supporters of Leopold Lopez said one of them suffered a heart attack during the riots.
The court ruling was promulgated by Leopold Lopez’s political party “Voluntad Popular (People’s Will)” and later confirmed by lawyers.
Earlier, the defense team of Leopold Lopez said that there were serious violations in the process: the judge heard 138 prosecution witnesses, but only one of the 50 witnesses and evidence presented by the defense.
His family says he has been in solitary confinement for most of his 19 months in prison and that his human rights have been violated.
Several other opposition leaders were also detained, and their fate divided opinion in Venezuela.
The US government and the UN have called for their release.
Reacting to the court’s verdict, US Assistant Secretary of State for Western Hemisphere Affairs Robert Jacobson said she was “deeply concerned” by the conviction.
Roberta Jacobson also called on the Venezuelan government to “defend democracy” in the country.
For many poor Venezuelans, Leopold Lopez is seen as a dangerous figure who incites violence and coups against the government and does not meet the needs of most ordinary people.
His critics note his involvement until 2002 in a failed coup attempt against the late President Hugo Chavez.
However, supporters of Leopold Lopez say he is a scapegoat for current President Nicolas Maduro during the economic crisis in Venezuela, which has led to a shortage of basic goods.
