Gardaí have renewed an appeal for information on the murder of a 21-year-old man who died after being attacked by a group of men ten years ago.

Paul Quinn, from Annamar, Cullyhanna, Co Armagh, was murdered on 20 October 2007 after being lured to sheds at Tullyvanus, Castleblaney, Co Monaghan where he was attacked by a group of eight to ten men.

He was subsequently admitted to Our Lady of Lourdes Hospital in Drogheda where he died of his injuries.

The renewed appeal for information from Crimestoppers and gardaí coincides with a review of the case by the Garda Serious Crime Review Team and a special programme which was broadcast last night by RTÉ's Prime Time.

Twenty three people have been arrested during the course of this investigation over the past ten years, gardaí have confirmed. Fourteen people were arrested in the Republic, while the PSNI have made nine arrests in Northern Ireland.

Gardaí have said the investigation is still active and that more than 700 statements have been obtained and nearly 2,000 individual lines of inquiry have been pursued.

Speaking today, Alan Cunningham, superintendent at Carrickmacross Garda Station said: "It's now ten years since Paul was murdered and we hope that with the passing of time some members of the public will be willing to come forward. We know that there are people out there who have the information to help us solve this case and bring the perpetrators to justice.

"We are particularly keen to hear from people in the South County Armagh and Monaghan areas. If a member of the public prefers to give the information without identifying themselves, they can call Crimestoppers on 1800 25 00 25. They will not be asked for any of their personal details. Otherwise information can be given to investigating gardaí at Carrickmacross Garda Station or any Garda station."

Calls to Crimestoppers are anonymous. Anybody with information can call on 1800 25 00 25.
