An Egyptian court sent on Tuesday 16 defendants to 10 years in maximum security prison for attempting to break into al-Waily police station last September.
The court also ordered the 16 defendants be placed under police observation for five years after their release from prison.
Seventeen defendants were charged with illegal assembly, possession of unlicensed weapons and vandalising public and private property. They were also accused of joining a “terrorist” organisation.
The 17th defendant’s criminal case was closed due to his death, reported state-run Al-Ahram.
According to the public prosecution, the 17 defendants were arrested outside Waily police station where they assembled to protest the arrest of demonstrators supporting the Muslim Brotherhood.
The Muslim Brotherhood has been staging protests since the military's ouster of former Islamist President Mohamed Mursi in July 2013.
The cabinet listed the Brotherhood as a terrorist organisation on December 25, one day after an explosion at the Daqahleya Security Headquarters which left 16 killed.
