N. Ireland secretary of state calls bomb 'callous and reckless attack' BELFAST, Northern Ireland, Oct. 25 (UPI) -- A letter bomb sent to Northern Ireland's chief constable has been intercepted, authorities said. Officials said an army bomb disposal team was sent to the main mail sorting office at Mallusk in north Belfast to examine and handle the device addressed to Matt Baggott, The Guardian reported Friday. Northern Ireland Secretary of State Theresa Villiers called the letter bomb a "callous and reckless attack." "Those responsible for this device have almost no support and have demonstrated a blatant disregard for the safety of those who could have been injured," Villiers said. The chief constable undertakes a challenging role in delivering community policing in a difficult environment.
