It has been almost three weeks since Ziad Bakir disappeared.

For his family, it means long, anxious days of waiting and wondering.

"Believe me, everything came to our mind," says his father, Mohammed, at home in the neighbourhood of Mohandiseen.

"Perhaps he has been killed, he has been injured, he has been detained."

Mohammed says he visited all the hospitals and morgues of Cairo, looking for his son, but found nothing.
