On 7 February 2008 , the Policing Board decided to appoint a panel of independent experts to re-review the police investigation of the Omagh bombing . Some of the relatives of the bombing victims criticised the decision , saying that an international public inquiry covering both the Republic of Ireland and Northern Ireland should be established instead . The review was to determine whether enough evidence existed for further prosecutions . It would also investigate the possible perjury of two police witnesses made during the trial of suspect Sean Hoey . Sinn Féin Policing Board member Alex Maskey stated that his party fully supported the families ' right to call for a " full cross-border independent inquiry " while the Policing Board had a " clear and legal obligation to scrutinise the police handling of the investigations . " He also stated : " We recognise that the board has a major responsibility in carrying out our duty in holding the PSNI to account in the interests of justice for the Omagh families . " On 22 November 2009 , a 400 lb car bomb was driven to the Policing Board building in Belfast . It partially exploded but no one was hurt . Republican dissidents tried to ambush policemen on the same day . The incident was one of several cross-border attacks carried out by hardline republicans in 2009 – 2010 ; others included the 2010 Newry car bombing
