. The second rider, a female in her early 30s, suffered serious injuries in another incident just before 2.10pm. She was transported by air ambulance at the same hospital. The event involved around 100 participants and 300 spectators. Durham Police said they had “no choice” but to shut down the meeting. “With two very serious incidents within little more than an hour, we felt there was little choice but to bring the event to a close,” police said. Tributes to the vistim rider began to be posted on a Facebook page connected to the venue with contributors referring to a “huge crash”. The venue’s owners later posted a note on the page saying the accident had happen when the man was riding his own motocross bike rather than one they provided.
