Unprecedented levels of co-operation between the PSNI and Garda have seen lives saved and more criminals caught on both sides of the border, police chiefs said.
PSNI Chief Constable Matt Baggott and Garda Commissioner Fachtna Murphy hailed the working relationship as they launched a new strategy to develop links further.
The Cross Border Policing Strategy is supported by Stormont's Department of Justice and the Republic's Department of Justice and Law Reform.
The blueprint reflects the desire of both law and order agencies to see more routine and faster transfer of evidence, improved communication channels for officers and the ability to bring more prosecutions against individuals for crimes committed in the neighbouring jurisdiction. As well as the obvious cross-border element to tackling dissident republicanism, both services work together to thwart human trafficking and smuggling.
Commissioner Murphy, whose force has thwarted a number of alleged dissident republican bomb plots planned for Northern Ireland in recent months, explained the rationale behind the strategy
"Terrorism, serious and organised crime, and local crime strike fear into the heart of communities and know no boundaries," he said. "It is therefore increasingly important that law enforcement agencies work in partnership to achieve the shared objective of keeping all of our communities safe. In recent months, through sharing information and intelligence, and by putting in place joint policing operations, many instances of terrorism, serious and organised crime and local crime have been prevented. This has undoubtedly saved lives, while ensuring those involved in such activity are identified and brought to justice."
Chief Constable Matt Baggott added: "I am deeply indebted to my colleagues in An Garda Siochana for the level of support and co-operation the PSNI receives on a daily basis. In the current climate it is even more pertinent for police officers to be able to utilise the experience, knowledge and technological capabilities available across both jurisdictions, to the best possible effect.
"The Cross Border Policing Strategy seeks to build on the existing co-operation and enhance the policing capabilities of both Police Services. Even stronger alliances in relation to cross border investigations and operations, intelligence sharing and security right through to communication and information technology, training and emergency planning will benefit both organisations. Over the next three years, we will work to implement objectives linked to such aspects."
Stormont's Justice Minister David Ford said co-operation between the PSNI and Garda was stronger than ever.
"However, determined not to rest on their laurels, the publication of this strategy reinforces their commitment to ensuring that policing co-operation on both sides of the border continues to operate at the highest level," he said. "It is inevitable that much of the focus is on terrorism, and of course the two police services will continue to work hand in hand to frustrate the efforts of those who want to drag us back to the past. This new Cross-Border Policing Strategy however shows the breadth of co-operation that exists across the full range of policing areas and shows that both services will use all tools available to them to ensure that those who seek to exploit the border for criminal ends will not succeed."
