Pair freed in prison officer murder probe

Two men being held in connection with the murder of prison officer David Black were released without charge tonight.

High profile republican Colin Duffy, 44, and a second man aged 29 were detained in Lurgan, Co Armagh, just miles from where Mr Black was ambushed on the M1 motorway on his way to work at the top security prison, near Lisburn, Co Antrim.
