Friends valiantly searched the waters for a young kayaker who became separated from the group and lost his life in a tragic accident.
At least three distress calls were made to the Dublin Coast Guard after Shane Murphy got into difficulty in the Inchavore River in the Wicklow Mountains.
It is understood that the 21-year-old was part of a group of seven people who were kayaking in the fast flowing water close to Lough Dan, just miles from Roundwood, Co Wicklow, on Thursday evening.
The heavy rain is believed to have contributed to the accident causing the river to swell considerably.
The young man from Baldoyle in north Dublin, was a second year student in Coláiste Dhúlaigh, where he was enrolled in the Outdoor Education Programme.
The college last night said that it was "with deep regret" they learned of the young man's death.
"We are deeply shocked and saddened by the loss of Shane, and offer our sympathy to his family," said the college principal Mary Hickie.
It is understood that the young man became separated from the group during the excursion, who then began to search for him.
At least three distress calls were made to the Dublin Coastguard shortly before 4pm on Thursday evening, and the Rescue 116 helicopter was dispatched to the scene from its base in Dublin Airport.
But, the tragic young man was unconscious and submerged in the water for at least 45 minutes before he was found.
It is believed that another member of the group performed CPR on him for at least 15 minutes before the rescue services arrived on the scene.
Mr Murphy was then airlifted from the scene and brought to Tallaght Hospital.
At least two others were also transferred to hospital, but their injuries are not believed to have been serious.
However, all were understood to have been suffering from shock.
Shane is survived by his parents Louise and Ray, his two brothers Stephen and Alex and sister Leah.
His funeral is set to take place on Monday morning.
The young man has been described as "a lovely lad", who was also a keen fisherman.
A spokesperson for Canoeing Ireland said last night that they were deeply upset to learn of Mr Murphy's tragic passing.
"On behalf of all canoeists in Ireland, we are very saddened by this loss. Our thoughts and sympathies are with the families at this time," they added.
