Former Mayor of San Cristóbal, Táchira state. Ceballos was arrested on March 18, 2014  and received an administrative sanction by the Supreme Court of Venezuela to 12 months in prison for his failure to follow an order to stop anti-government protesters from organizing barricades in the streets of San Cristóbal. From 2014 to 2015, Ceballos was transferred to different prisons. After his last transfer, on May 26, 2016, Ceballos started a hunger strike that lasted 20 days, along with Leopoldo López. He was placed under house arrest in August 2015. On August 27, 2016, Ceballos was once again transferred to El Helicoide, a jail he previously served time in. This time, he was accused of planning an escape. He was isolated at all times, according to a report by ONG Amnesty International released in December 2017. He was freed on June 1, 2018.
