Police are appealing for witnesses following a serious car accident near the Northamptonshire border.
Northamptonshire officers were called to the Aynho Road, which runs from Ayhno to Adderbury in Oxfordshire, at lunchtime yesterday after a head-on collision between two vehicles.
As yet police have not released details of any injuries.
The stretch of road was closed while a traffic collision unit carried out tests and the scene was cleared.
Police said this morning that a separate accident had taken place on the same road this morning, leading to another road closure.
Witnesses or anyone with information can contact police on 101 or Crimestoppers anonymously on 0800 555 111.
