A 67-year-old man has been arrested in connection with the murder of Joseph James Porter in 1979.
Mr Porter was a farmer and member of the Ulster Defence Regiment (UDR), an infantry regiment of the British Army.
He was shot dead by the Provisional IRA close to his home in Mountnorris on June 24, 1979 – 45 years ago today.
Detectives from An Garda Síochána arrested the suspect in Co Cavan.
He has been arrested on suspicion of murder, firearms offences and membership of a proscribed organisation.
The arrest was made under a Trade and Co-operation Agreement (TaCA) Warrant as part of a joint operation with the PSNI.
He is expected to appear at Dublin High Court later today, Monday, June 24.
A police spokesperson said: “The PSNI’s Legacy Investigation Branch has been liaising closely with An Garda Siochana and today’s arrest further demonstrates the benefits of joint working between police services and other national partner agencies.”
A decision to prosecute this individual was issued by the Public Prosecution Service prior to the commencement of the Northern Ireland (Legacy and Reconciliation) Act 2023 on May 1, 2024.
