Irish Coast Guard helicopter Rescue 116 was on hand Wednesday to save a woman seen in the water close to cliffs near the Baily Lighthouse on Howth Head.
SAR Ireland reports that the helicopter was on a training exercise just up the coast in Malahide when passers-by raised the alarm with the Marine Rescue Coordination Centre (MRCC).
Rescue 116 sped to the scene and after a short low-level search the woman was spotted and taken to a waiting ambulance at the coastguard base for treatment.
The Irish Times says Howth gardaí are investigating the incident.
