Jorge Emilio Esquivel Muñoz, better known as "El Yorch", was taken to the Public Prosecutor's Office to testify.
The activist, who had taken the auditorium Justo Sierra of the Faculty of Philosophy of the National Autonomous University of Mexico (UNAM), was arrested yesterday at 22:40 hrs.
After his arrest activists barricaded the outer loop of Ciudad Universitaria around the Faculty of Philosophy for three hours. The barricades have been since removed.
