A new cross-Border taskforce is to be established to investigate organised crime on both sides of the Border, including paramilitarism.
The new body will be funded by Governments in Dublin and Belfast and will be led by senior officials within An Garda Síochána and the Police Service of Northern Ireland.
Minister for Justice Frances Fitzgerald said issues of tobacco smuggling, fuel laundering, fraud, cyber crime and human trafficking will be dealt with in a more focused way by the taskforce.
She said: “This arises from the Fresh Start agreement. This is a particular initiative to tackle cross-Border crime.
‘Criminals don’t respect borders’
“We know criminals don’t respect the borders, whether we are talking about in Ireland or internationally, and it is to deal effectively with the disruption to communities.”
The taskforce will work with the Revenue Commissioners and HM Revenue and Customs and will seek to end the exploitation of the borders between the two jurisdictions.
First Minister Peter Robinson said the taskforce will begin its work next month.
He said criminal gangs have used the Border for their benefit, adding that the taskforce would assist in ending paramilitarism.
Deputy First Minister Martin McGuinness said the activities of those who attempt to “plunge us back into the past need to be confronted”.
He said: “Criminality is a scourge on our communities, North and South, and we must be both united and relentless in our pursuit of these criminals.
"This Joint Agency Task Force provides renewed energy, focus and additional mechanisms for us to work collectively for the greater good of people across the island of Ireland."
