It will be practically impossible to police all the Border crossings in the event of a hard Brexit, a leading garda has warned.
Chief Superintendent Christy Mangan described the prospect of a hard Border as a "calamity" and a "doomsday scenario" for police work.
He said: "There are 36 Border crossing points in Louth and we cannot man every one in a Brexit situation, it is nigh-on impossible to do.
"It would be a doomsday type of scenario because of the calamity it would bring to gardaí working in Louth if there was a hard Brexit."
Chief Supt Mangan said that in order to police the Border properly, gardaí would need a considerable increase in physical resources.
"I am talking not just about people, but also physical buildings, support in IT and other areas," he said.
"I do not have enough resources now so I definitely would not have enough in the event of a hard Brexit, unless this is addressed.
"My detective inspector is due to retire shortly and that will leave vacancies for two detective inspectors in this division. I require another seven inspectors because I should have nine in total."
Detective Inspector Patrick Marry, who has solved more than a dozen major crimes including murders over his 33-year career, is the member of the force due to retire.
The two remaining inspectors have 61 portfolios between them that previously were shared among seven.
However, Chief Supt Mangan said that, regardless of what sort of Brexit materialised, "co-operation with the PSNI will continue. They rely on us to continue enquiries down here and vice-versa."
