CAIRO: Egyptian April 6 Movement will stage a protest outside the office of the Public Prosecution on Wednesday over the disappearance of one of its members. They will also stage an open-ended sit-in if the member of political bureau of the April 6 Movement, Sherif el-Roubi, does not appear. El-Roubi has been missing since October 22. "We all exerted efforts to find our fellow member but in vain and we have nothing except protesting and staging open-ended sit-in until he appears again," said April 6 Movement spokesman, Tareq el-Kholi.
