Three hundred and thirty-six protesters were also detained pending investigation following clashes that erupted during a pro-Morsi protest in the Cairo district of Bab El-Shareya and downtown Cairo's Ramses Square.
Detainees face charges of rioting and vandalising private property.
Seventy protesters were held for 15 days pending investigation on charges of targeting police officers at El-Azbakeya police station in central Cairo during demonstrations also on Monday night.
Police forces clashed with pro-Morsi demonstrators in Ramses Square on Monday firing teargas and birdshot to clear the square for traffic.
The Muslim Brotherhood, from which deposed president Morsi hails, had called for mass demonstrations on Monday and throughout the week to demand his reinstatement following the popularly-backed military overthrow of the elected president on 3 July.
