A number of officers from the Police Service of Northern Ireland (PSNI) will be sent to Scotland to help police the visit of US President Donald Trump later this week.
The request for "mutual aid" was made by Police Scotland, ahead of Mr Trump's trip to his golf courses in Turnberry and Aberdeen.
The semi-private visit will also involve a meeting with UK Prime Minister Keir Starmer and Scottish First Minister John Swinney.
In a statement the PSNI said: "A number of officers from the Police Service of Northern Ireland will travel to Scotland in the coming days to support Police Scotland colleagues in the planning and safe delivery of policing around the US presidential visit.
"The deployment follows a request for mutual aid via the National Police Co-ordination Centre.
"The full cost of the deployment will be recovered from Police Scotland."
Mutual aid requests are not unusual, with Police Scotland providing assistance to the PSNI during the riots in Ballymena a number of weeks ago.
The PSNI would not comment on how many officers would be deployed to Scotland or the roles they would be fulfilling for "operational reasons".
Donald Trump's Scottish golf courses have been targeted by protesters in the past and a number of demonstrations are planned across Scotland during the weekend.
