"Leopoldo [Lopez] is at Ramo Verde [military prison], the house arrest was lifted without presenting an arrest warrant, his lawyer was not informed," Velasquez said.
Earlier in the day, Venezuelan authorities arrested Lopez and Antonio Ledezma, two opposition figures, amid mass anti-government protests, taking them from their homes and giving no information as to where they would be kept.
On Sunday, Venezuela held the election of the Constituent Assembly, which will be charged with rewriting the constitution. The opposition did not recognize the results of the vote, saying the decision to convene the assembly should be made via referendum. The series of protests has so far claimed the lives of over 120 people.
