A man arrested in connection with a serious collision in Lechlade on Saturday (30 May) has been released under investigation while enquiries continue.
The 25-year-old man, from Hereford, was arrested on suspicion of driving while over the prescribed alcohol limit and causing serious injury by dangerous driving.
The collision happened shortly before 10pm on the A361 Thames Street Half Penny bridge in Lechlade.
A white Mercedes coupe that was travelling from Lechlade towards Swindon and a dark blue Audi A5 hatchback travelling in the opposite direction collided in the centre of the bridge.
A pedestrian, a 46-year-old woman from the Lechlade area who was on the bridge, was hit by one of the cars.
She was taken to John Radcliffe Hospital in Oxford with serious injuries that are not life threatening.
The driver of the Mercedes was taken to the Great Western Hospital in Swindon with non-serious injuries.
However the condition of a man who was the passenger in the Mercedes has worsened since the incident and his injuries are now considered serious.
He remains at the Great Western Hospital in Swindon.
Officers investigating the collision would like to speak to anyone who they’ve not spoken to already, who may have witnessed the collision or who may have seen either vehicles shortly before the collision occurred.
Officers would also like to speak to anyone who may have dash-cam footage that will assist them in establishing what happened.
Anyone with information is asked to call 101 and quote incident 560 of 30 May.
