Trainer Gordon Elliott has issued an apology after an image of him sitting on a dead horse appeared on social media this weekend.
The Irish Horseracing Regulatory Board launched an investigation into the photo yesterday.
Elliott confirmed the photo's legitimacy in a statement last night, adding that he is cooperating fully with the IHRB.
The trainer says the image was taken some time ago, and says has apologised "profoundly for any offence caused".
In the picture, Elliott appears to be making the "peace" gesture with his fingers after the sudden death of one of his horses on the gallops.
However, in his statement, he claims he was gesturing to a colleague to wait until he was finished with his phonecall, adding that "the welfare of each and every horse under my care is paramount and has been central to the success that we have enjoyed here at Cullentra".
The IHRB are yet to comment on Elliott's admission.
Read the Gordon Elliott apology in full below:
"I would like to address the speculation and rumours that have been rife since an old photo of me began circulating on social media yesterday afternoon.
"Firstly, I apologise profoundly for any offence that this photo has caused and can categorically state that the welfare of each and every horse under my care is paramount and has been central to the success that we have enjoyed here at Cullentra.
"The photo in question was taken some time ago and occurred after a horse had died of an apparent heart attack on the gallops. I appreciate that an initial viewing of this photo suggests it is a callous and staged photo but nothing could be further from the truth.
"At what was a sad time, which it is when any horse under my care passes away, my initial reaction was to get the body removed from where it was positioned. I was standing over the horse waiting to help with the removal of the body, in the course of which, to my memory I received a call and, without thinking, I sat down to take it. Hearing a shout from one of my team, I gestured to wait until I was finished. Such background information may seem trivial at this time and will not allay the concerns of many people both within and outside the world of horse racing.
"However, I feel it is important to provide people with some context surrounding this photo. To the racing community, to anyone who has worked with and loves horses and to anyone offended by this image I cannot apologise enough.
"Horse welfare and the care and attention to detail involved is absolutely at the core of everything we do here and both myself and all of my team pride ourselves on those standards.
"Again I apologise for any offence caused and ask people to consider this statement as opposed to the various falsehoods and misinformation being circulated on social media.
"At this time I would like to stress that I continue to extend my full cooperation with the ongoing IHRB investigation."
