[Dawn] ISLAMABAD: Local police raided over a dozen houses across the city to pick up sectarian Muslim clerics on their watch list but in vain and only to retreat quickly in the face of the menacing mood of their supporters.Independent sources told Dawn that the police were so keen to avoid a confrontation that even the only cleric the police caught hold of in the predawn raids -- Ibrahim Haidri from his house near Bari Imam -- was set free after a few hours.
