Egyptian police had arrested the owner of a publishing house for printing a book about Mohamed ElBaradei, the former chief of the International Atomic Energy Agency, his family said on Sunday. The police had raided Ahmed Mehana's house near Cairo in search of the book, they added. They seized his personal computer and took Mehana with them, said his mother. There was no immediate comment from police. Mehana, who is also a blogger, published a book titled “ElBaradei and Dream of the Green Revolution”, which his author, Kamal Ghabriel, says is a collection of articles already posted on websites. “These articles give an objective insight into the issue of ElBaradei with some criticism of his elite supporters,” adds Ghabriel. ElBaradei, 67, is a potential presidential candidate, who is campaigning for drastic constiutional changes.
