ALEXANDRIA, Egypt (Reuters) - In Egypt's second city, medical student Ahmed Nabil lives in fear that the police may come and arrest him any day. As a member of the Muslim Brotherhood, he is part of a movement facing an onslaught by the security forces which toppled Islamist President Mohamed Mursi in July.

"These days we can be picked up at any time," said Nabil, whose parents are also members of the organisation, Egypt's oldest Islamist movement and a supporter of Mursi.
