The publisher of the new book about Mohamed ElBaradei, the former UN nuclear watchdog, was arrested by the Egyptian authorities on Saturday.  Egyptian officials raided Ahmed Mahanna’s house a week after he released a book lauding ElBaradei who has launched a campaign for political reform and hinted he may challenge Egyptian President Hosni Mubarak in an election due in 2011.  Egyptian officials did not state a reason for detaining Mahanna, who was released the next day.
