PSNI alongside their emergency colleagues in the RNLI, HM Coastguard and other agencies will be carrying out a multi-agency emergency training exercise in the Dundrum area on Saturday 9 September.
There will be police and emergency services activity in the area, both on land and on the water, throughout the day.
Members of the public need not be alarmed as this is purely an emergency training exercise.
Please note there are no plans to use any pyrotechnics (flares/smoke) during the exercise. If members of the public see any flares and/or smoke they should be treated as a real emergency and call 999 immediately.
