The number of Muslim Brotherhood members arrested since last week, in the latest crackdown by the Egyptian authorities, has risen to 22. Among the latest member of the banned but tolerated group is Abdul Moneim Mahmud, 26, a leading figure in the brotherhood in the city of Alexandria. According to the movement's spokesman, Essam al-Aryan, the security forces on Tuesday made a threatening request to the parents of Mahmud to hand him over. He described this as a "new and dangerous intimidation strategy," aimed at striking the families of members. In the past, arrests were normally made at night, with police bursting into the homes of the brotherhood members. But in recent blitzes, the security forces have stopped the Islamic militants in public places, including popular cafes in the capital, provoking fears that the authorities were taking a harsher line. In particular, Ayman Abul Ghani was arrested along with his wife when he went to collect his children from school in Nasser City on the outskirts of Cairo.
