A multi-vehicle collision has resulted in approximately 11 casualties in an incident that has led police to close a major road on the outskirts of Chester.

Emergency services say a grey Peugeot 5008, a red BMW and a grey Citroen Belingo are involved in the accident which happened about 1.50pm today (Wednesday, July 22) on the A51 near Tarvin, on the stretch between the A51-A54 roundabout and the Stamford Bridge Inn.

One vehicle is on its roof and there are reports of people being trapped, with a number of casualties being helped from their cars. Police, fire and ambulance crews are in attendance including two North West Air Ambulance helicopters.

Cheshire Police spokesman Daniel Hinde said: “There are believed to be approximately 11 casualties.”

However, police do not believe there are any serious injuries based on current information.

The Countess of Chester Hospital told The Chronicle it had not been informed of a major incident being declared, which can happen when a large influx of casualties is expected.

Police have closed the A51 in both directions between the Tarvin Roundabout and at the A55 Vicars Cross Roundabout to prevent traffic heading down the route and ‘getting stuck’.

The collision is causing traffic delays and motorists are advised to avoid the area.

A North West Ambulance Service NHS Trust spokesperson said: "At 13.46 today we received a call to reports of a multi car RTC in Tarvin, Cheshire. So far, we have despatched two rapid response vehicles, three ambulances, two helimed units, two intermediate care vehicles and a number of operational managers to the scene with the first crews arriving at 13.58.

"We are currently assessing the scene and working closely with other members of the emergency services, with our priority being to ensure people receive the medical help they need as quickly as possible.

"Our primary role is to assess the level and nature of injuries, and ensure that those people most in need are treated first and taken to hospital. Countess of Chester Hospital has been alerted and is preparing to receive patients. Other hospitals may also be on standby.

"At this stage, it is too early for us to confirm the number of casualties."
