A young man died in a motocross accident after his scrambler bike struck a tree.
The fatal accident occurred around 8pm on Saturday as Stephen O'Callaghan (21) was riding his scrambler bike on a woodland track outside Blarney, Co Cork.
Mr O'Callaghan lived just a short distance away at the Riverview Estate.
The track is near the old Muskerry tram line and is not far from the Blarney Castle estate.
A public track which is popular with walkers and cyclists, the route leads through woodland and is lined in parts by large trees.
Gardaí said it appears that the young man lost control of the scrambler bike on a steep section of the track and hit a tree.
He was thrown off the bike and landed close to a nearby stream, suffering critical injuries.
Another young man, who went to check on Mr O'Callaghan, made the grim discovery and immediately raised the alarm.
Emergency services raced to the scene but, despite desperate efforts by paramedics to stabilise the young man's condition, he was pronounced dead before he could be taken to Cork University Hospital (CUH).
No other vehicle was involved.
Blarney gardaí are treating the incident as a tragic accident.
However, a full technical examination was carried out at the scene by Garda forensic experts.
A file will now be prepared for the Cork coroner.
The Office of the State Pathologist was informed and a full post-mortem examination will be carried out at CUH.
Blarney locals expressed deep shock at the tragedy.
Mr O'Callaghan worked at a local garage and was described as "a popular, hard-working young man from a respected local family".
He was noted for his happy demeanour and wide circle of friends.
The young man had a lifelong interest in outdoor sports and motorcycles.
A total of 47 people have died on Irish roads this year - eight more than for the same period last year.
