Egyptian authorities have released the last batch of Christians detained for injuring at least 60 policemen during clashes last month, judicial sources said Tuesday.
The nine detainees were allowed to return to their homes after posting bail of 50 dollars each, the sources added.
The majority of the policemen were injured on December 8 when around 1,000 Christians who were staging a sit-in at the compound of the main Coptic cathedral in Cairo threw rocks at them.
The demonstrators were protesting at the disappearance of a priest's wife north of Cairo.
They claimed that 48-year-old Wafaa Constantine was abducted by her Muslim boss and forced to convert to Islam, with the complicity of the state's security services.
Nearly 400 Egyptian Christians also demonstrated on December 5 at the cathedral, calling on President Hosni Mubarak to intervene.
The head of Egypt's Coptic Church, Pope Shenuda III, later holed himself up in a desert monastery to protest the arrest of Christians.
A total of 34 were detained in connection with the unrest. Thirteen, nearly all minors and students, were released on December 21 and 10 more on December 30.
Constantine resurfaced a few days after her disappearance. She was later quoted by the press as telling investigators: "She was born and would die a Chriastian."
