A cross-county emergency service operation is reportedly under way after a crash involving two motorbikes and a car in the Yorkshire Dales.
An air ambulance took one person to hospital while another was taken by regular ambulance after the incident on the B6255 Newby Head Pass, near Newby Head Farm between Ingleton and Hawes.
The road is currently closed between Hawes and the turn off for Dent to allow the Collision Investigation Unit to take a full look of the scene.
Drivers are advised to avoid the area.
According to a social media post by the force, it has received help from North Yorkshire Fire and Rescue Service, Yorkshire Air Ambulance, Yorkshire Ambulance Service as well as West Yorkshire Police, Lancashire Police and Cleveland Police.
