Three people have been rescued by Coast Guard and lifeboat personnel after the jet ski they were travelling on crashed into the east pier in Dún Laoghaire.
The Marine Rescue Coordination Centre received a call from a member of the public just before 4pm this afternoon saying that all three people had gone into the water following the crash.
The Dún Laoghaire Inshore lifeboat and members of the local Coast Guard unit responded, and all three casualties were recovered from the water.
Dún Laoghaire RNLI said it was preparing to assist the three people after being alerted via their pagers.
They were informed that the casualties had been picked up by a rib (rigid inflatable boat).
The launch was stood down and two of the crew went to the pontoon at National Yacht Club to meet the rib and assess the casualties.
Two of the casualties required care and one received urgent first-aid attention while the National Ambulance Service was making its way to the scene.
They were then passed into the hands of paramedics and one was transported to hospital.
The lifeboat volunteers attended the scene for over an hour.
In a statement, the Department of Transport said: "At approximately 3.50 pm today, the Marine Rescue Coordination Centre (MRCC) Dublin received a report from a member of the public regarding a jet ski incident at Dun Laoghaire East Pier.
"The caller reported that a jet ski with three people onboard had collided with the pier, resulting in all three individuals entering the water. The Irish Coast Guard Dun Laoghaire inshore lifeboat and the local Coast Guard unit were immediately tasked to the scene. All three casualties were recovered from the water, with two transported by ambulance to hospital for further medical assessment."
