Tributes paid to quad bike racer Daniel Roch
A teenage quad biker from Pembrokeshire who died during an event on Sunday had been racing competitively for several years, said a local councillor.
Daniel Roch, 19, from Narberth was at the Talsarn motocross track near Lampeter in Ceredigion.
Dyfed-Powys Police are asking anyone who filmed the event to contact them.
Councillor Elwyn Morse, who has known Daniel all his life, said: "The quad racing has been a big part of his life."
No-one else was hurt in the incident.
Dyfed-Powys Police confirmed an inquest into the death has been opened and adjourned until a later date.
The Health and Safety Executive has also been informed.
Police were called to the race, run by Dredgers Motocross Club in Llanelli, at around midday.
