Anas El-Beltagy, a student, was arrested in Nasr City in eastern Cairo along with two other students. All three students have been accused of rioting and violent acts at Cairo University and Ain Shams University. Authorities claim that at the time of their arrest, the young men were in possession of bird shot pellets, video cameras, and banners that bore anti-army and pro-Muslim Brotherhood slogans.
Tensions between security forces and Muslim Brotherhood supporters spiked following the military's removal of President Mohamed Morsi, a Muslim Brotherhood member, in July 2013.
The elder El-Beltagy was arrested in late August following Morsi's removal. Another son, 20, was detained in August for inciting violence and released. A 17-year old daughter was killed in August when security forces raided a pro-Morsi protest camp.
The three students' arrest follows a renewed crackdown on the Muslim Brotherhood organization, which the Egyptian government declared a terrorist organization last week. On Sunday, the police arrested four Al Jazeera journalists, accusing them of "broadcasting news that threatens internal security and spreading false news" through their contact with and reporting on the Muslim Brotherhood organization.
