Gardaí this morning made another arrest in connection with the murder of Armagh man Paul Quinn.
A man, aged in his 30s, was arrested during searches at an undisclosed location this morning. He is being held at a Garda station in Monaghan under Section 30 of the Offences Against the State Act.
Paul Quinn (21), from Cullyhanna, was beaten to death by a masked gang in a Co Monaghan barn in October.
Three men arrested by gardaí on Tuesday in connection with the killing have been released without charge. The men – aged in their 20s and 30s – had been held at Garda stations in Monaghan and in Carrickmacross for 72 hours before being released shortly before midnight last night.
In the North, the PSNI are still questioning three men arrested yesterday.
The men, two aged in their 30s and one in his 40s, were arrested in south Armagh in what detectives said was the second phase of an operation in support of the Garda investigation. The PSNI had earlier released two other men.
Ten men have now been arrested in total in the past three days by police on both sides of the Border.
The International Monitoring Commission has blamed former Provisional IRA members or associates for the murder of Mr Quinn.
An inquest opened briefly in Dundalk last month to issue a death certificate to his family, and it was adjourned due to the police investigation.
