Popular satirist Bassem Youseef is being questioned by prosecutors in Egypt over allegations of insulting Islam and President Mohammed Morsi.
Mr Youssef arrived at the public prosecutor's office this morning, after a warrant was issued for his arrest yesterday.
Youseef, who shot to fame after winning a large number of followers online for his critical and witty look at public figures in Egypt following the 2011 uprising, has faced several complaints over his show El Bernam (The Programme).
His show is broadcast three times a week on one of Egypt's independent satellite stations. His recent portrayals of Morsi as a Pharaoh, or "Super Morsi", have angered Islamists and the president's supporters.
Mr Youssef's case is also seen as the latest in a string of prosecution actions against opponents of the president and the movement that supports him, the Muslim Brotherhood.
