Members of the Gardaí attended the scene at Blackrock Pier this afternoon after being alerted to the dead animal by members of the public.
A Garda spokesperson said:
"Initial reports are, that a horse became distressed and died having returned to the pier at Blackrock following a swim. It’s understood the horse was in the control of its owner at the time. Gardaí attended at the scene shortly after 4pm. Enquires into the matter are ongoing."
Local Fine Gael Councillor Des Cahill was shocked to learn a horse had died in the water at the pier in Blackrock.
“That’s very sad. It’s horrible that it happened. I’m at a loss for words,” he said.
“I have seen horses in the water there previously, attended, and being exercised or washed, but it’s certainly not a regular occurrence. I saw that, probably only twice in the last 12 months. So, it’s certainly not a regular occurrence,” he added.
“How the poor animal died I don’t know.”
