We were running an abseil from the top of Fine View Wall (roughly down Mynydd Marian VS 4C) when we heard someone bounce (telltale jangle of gear and dull thuds).

The group that had the incident was a father, c 17yo daughter and c. 5 yo son. The son had been top toped (although not on a named route) and the father had been doing occasional solos. The incident occurred on one of these solos where the father (climber) pulled on a "dragon's tooth" and it came off in his hand, sending him backwards. This was in front of our Scouts who had already abseiled and his own children. One of our leaders provided First Aid, and it was clear that the father was badly injured from his fall. After a short while the father proceded to drive his family away.
