Murder of prison officer David Black: two men held
Two men remained in police custody last night after they were arrested in connection with the murder of a Northern Ireland prison officer.
The men, aged 51 and 34, were detained in the Republic over the killing of David Black in a drive-by gun attack on the M1 last year.
The father-of-two was shot dead as he drove from his home in Cookstown to Maghaberry Prison just outside Lisburn in November 2012.
Police in the Republic said they arrested the men as part of investigations into dissident republican activities and the murder.
A number of searches were carried out in counties Leitrim and Cavan.
Last month the PSNI launched a fresh appeal for information regarding Mr Black's murder.
Detective Chief Inspector Richard Harkness said: "I am making a particular appeal to people in Lurgan to think about what they know and what they saw.
"I would remind people there is a reward of up to £10,000 available for information leading to the arrest and conviction of those responsible."
