Irish Nationalist Arrested over Prison Guard's Killing
Had been acquitted earlier in the year of the murder of two British soldiers
An Irish nationalist acquitted earlier this year of the murder of two British soldiers in Northern Ireland was arrested on Friday in connection with the fatal shooting of a prison officer, a security source said.
The murder of David Black, 52, on Thursday was the first killing of a Northern Irish prison officer in almost 20 years and the fifth fatal attack on a member of the security establishment since the 1998 Good Friday peace deal.
The pact largely ended three decades of sectarian conflict in Northern Ireland between Protestants loyal to British rule and mostly Roman Catholic nationalists who want to unite with the southern Irish republic.
