An Egyptian investigative judge ordered the release Sunday of a prominent blogger detained nearly two months ago by the ruling military, which had accused him of attacking soldiers during deadly clashes in October.

Alaa Abdel-Fattah's father, Ahmed Seif, told The Associated Press his son would remain in custody for several more hours until the paperwork has been completed. He said his son has been banned from travel abroad.

Abdel-Fattah's sister, activist Mona Seif, told the AP her brother was on his way to the Egyptian capital's security headquarters where he would be freed later in the day.

Military prosecutors detained Abdel-Fattah on Oct. 30 after he refused to answer questions about their allegations that he played a role in the clashes.

The violence on Oct. 9 began when groups of stone-throwers attacked a crowd of Coptic Christians protesting an attack on a church in southern Egypt. TV footage showed the military moving in with force, including using armored vehicles to run over the crowds.
