SASKATOON, Saskatchewan, (Reuters) – Six high-risk  prisoners escaped a Canadian jail last summer after spending  four months chipping a path to freedom with nail clippers and  other makeshift tools, according to a government report  released yesterday.

The prisoners, four of whom faced murder charges, used  their tools to remove a heating grill and steel plate and win  access to a brick exterior wall.
While some inmates played cards at a carefully positioned  table to block the guards’ view, others chipped away at the  wall, finally breaking through with a steel shower rod. They  then used braided blankets and bedsheets to scale a wall of the  compound and escape.
