The Nasr City Misdemeanor Court, held at the Police Academy and headed by Judge Ahmed Magdy, sentenced on Sunday 36 Al-Azhar University students belonging to the Muslim Brotherhood to four years in prison.
The court placed them under police surveillance for another four years and fined each LE30,000.
A suspect, who is a journalist at Yaqeen news network, was acquitted.
The journalist's lawyer said the prosecutor accused his client after the session of taking footage on his camera with the intention of distributing them to tarnish the image of Egypt.
He added that the journalist was released due to lack of evidence.
The convicted defendants faced charges of rioting, bullying, blocking roads, assaulting the police, resisting arrest, demonstrating without a permit from the Interior Ministry, joining an armed terrorist group, aiming to disturb public peace and possessing Molotov cocktails.
