As of Monday, 329 protesters have been detained on charges of rioting during clashes with security forces on Mohamed Mahmoud Street and Qasr al-Aini Street, said a security source.
Ninety of those detained have been formally arrested and are facing legal charges, the source told state-owned news source MENA. Another 74 protesters who were under the age of 18 were released to relatives, and another 165 detainees were released without charge.
The source also claimed that 199 police officers have been injured in the clashes.
Violent confrontations have been taking place between protesters and security forces on the streets around the Interior Ministry for the past 10 days. The two groups began hurling stones and Molotov cocktails at each other on the first day of the commemoration of the 2011 Mohamed Mahmoud clashes.
The violence escalated on Friday, the day after President Mohamed Morsy issued a new constitutional declaration that granted him unprecedented powers and made his rulings legally uncontestable.
