CEP Senior Advisor Ian Acheson writes: "An off-duty senior detective in Northern Ireland’s police service was ambushed last night by masked gunmen as he helped at a football coaching event in Omagh, Country Tyrone. Two assailants fired at least four bullets into Detective Chief Inspector John Caldwell, shooting him on the ground as his terrified son looked on. He remains critically ill in hospital. PSNI detectives investigating his attempted murder are pursuing dissident republican terrorists in the ‘New IRA’ as a strong line of inquiry. Three men have been arrested."
