Central Beacons were alerted during a fundraising / publicity event at Pont yr Daf by a group of walkers that one of their party was missing. The missing 30 year old male had becoming separated from his party. Concerns were raised as the missing person was know to have a serious medical condition thus additional assistance was sought from colleagues at Brecon Mountain Rescue. The missing person arrived safely back at Pont yr Daf three hours later unaware of the search for him.
