A SERIOUS accident on the A350 leading into Chippenham was causing massive traffic jams in the town.

The accident is believed to have happened within the last hour, and two fire engines and an ambulance were at the scene.

A passer-by said: “It looks like someone has been cut out of the car.

“The entire roof has been lifted off. It’s going to cause traffic havoc throughout the town, particularly as it’s so close to rush hour.

"Already we’re just sitting in traffic. There’s no one still in the car, so it seems pretty likely an ambulance has already taken the person inside to hospital.

"Traffic is really building up around the area.”
