Gardaí are urging anyone who has video footage of the Cork Ironman event that saw two people die in the water to make contact with them.

44-year-old Meath man Brendan Wall and 64-year-old Canadian Ivan Chittenden both died at the event in Youghal on August 20th.

The cause of their deaths remains unknown and Gardaí have said post-mortem results combined with witness statements will form part of a file being prepared for the coroner.

In a statement this morning, investigators said they are assisting the Cork County Coroner with its investigation.

They are asking anyone who was at the swimming section of the event and may have video footage to contact them via email at Midleton.IncidentRoom@garda.ie or by phone at 021-4621550.

A Garda spokesperson said people should not submit the footage – noting that officers will, “make contact with them to arrange for the appropriate collection of any video footage”.

After the tragedy, a dispute emerged between the organisers of the event and Ireland’s triathlon governing body.

Triathlon Ireland said the following day that its officials refused to sanction the race because of adverse conditions.

Later, however, Ironman Ireland said that decision was not communicated to on-site officials until "several hours after the swim was completed".

However, organisers Ironman Ireland said on Tuesday that was not communicated to on-site officials until "several hours after the swim was completed".

Triathlon Ireland then insisted once again that its officials told their Ironman counterparts that it was not possible to sanction the race, “before the start of the race”.
