Two men have been arrested after a car drove into a tent on a campsite in North Wales, injuring four campers, police said.
One of the campers, a woman, has been left with critical injuries in the overnight incident at the Rhyd y Galen campsite near Caernarfon.
Detective chief inspector Sion Williams said: “This was a terrifying event for people who should have felt safe in their tents.
“North Wales Police are supporting those involved and our thoughts are with the family of the woman who has been seriously injured.
“I would like to thank those members of the public who have helped us, but if anyone has not been spoken to yet and has any information which could assist, then please contact us.”
The Roads Policing Unit is working with detectives to establish exactly what happened, he added.
