POLICE this morning towed away a green taxi matching the description of the car they are looking for in connection with their hunt for Sian O'Callaghan.

The vehicle was loaded onto the back of a lorry and taken away after police swooped on the car park of ASDA Wal*Mart at the Orbital shopping centre in North Swindon.

Officers at the scene were unable to confirm whether any arrests were made at the scene.
