Egypt Muslim Brotherhood leader Mohammed Badie held
The spiritual leader of the Muslim Brotherhood, General Guide Mohammed Badie, has been arrested in Cairo, Egyptian officials say.
Reports said he was detained at a residential flat in Nasr City.
The flat is near the site of a six-week protest by Brotherhood supporters which was bloodily broken up last week.
Mr Badie had been on the run as interim authorities in Egypt try to suppress protests at the ousting of President Mohammed Morsi.
His arrest comes days after his son Ammar Badie, 38, was shot dead during protests in the capital's Ramses Square.
A state of emergency is in force in Egypt amid turmoil following a crackdown on Islamists in which hundreds have died.
Hundreds of members of the Muslim Brotherhood have been detained over recent days.
