A bystander saved a person's life in North Dublin overnight.
The person was resuscitated in Skerries by CPR.
Earlier in the day, another person was saved by the public when they went into cardiac arrest on a beach in Portmarnock.

Firefighter/Ps from Kilbarrack teamed with @IrishCoastGuard and NAS today to respond to a cardiac arrest on the beach in Portmarnock. There was a successful resuscitation on scene.
This why we ask that emergency access to beaches and amenities are maintained at all times. pic.twitter.com/n7Yr7vbRj6— Dublin Fire Brigade (@DubFireBrigade) March 24, 2020
