Secret Pakistan detention system revealed

Pakistan’s military and intelligence agencies, apparently trying to avoid acknowledging an elaborate secret detention system, have quietly set free nearly 100 men suspected of links to terrorism, few of whom were charged, human rights groups and lawyers here say.
Those released, they say, are some of the nearly 500 Pakistanis presumed to have disappeared into the hands of the Pakistani intelligence agencies cooperating with Washington’s fight against terrorism since 2001.
