The Giza Prosecution Office renewed the detention of eight Cairo University students for another 15 days on Thursday pending investigations, the Association for Freedom of Thought and Expression (AFTE) said.
Security forces arrested the eight students from each of their homes at dawn on 21 April, after Cairo University campus clashes between police and student protesters.
Since then, the detainees have been receiving continuous 15-day detention pending investigations.
Egyptian security forces are notorious for this arrest tactic, and have been called “dawn visitors” since the days of former president Hosni Mubarak.
The students are accused of belonging to student group Students Against the Coup (SAC), of protesting without permission, attacking public employees, and destroying public and private property.
Authorities have undertaken a fierce crackdown on students over the past two years, as security forces have killed dozens of students on-campus and arrested hundreds more, according to AFTE.
