A MAN has been arrested after five vehicles crashed in two collisions on the Prince of Wales Bridge, which links England to south Wales.

On Wednesday, at around 4.20pm a white Ford Transit van collided with a Citroen C4 on the westbound carriageway and immediately afterwards, a second crash happened on the eastbound carriageway, involving a Peugeot Boxer van, a Renault Master van and a Skoda Fabia.

The Ford Transit van failed to stop at the scene, but was found on Thursday morning in Newport.

A 44-year-old man from the city was arrested on suspicion of dangerous driving, perverting the course of justice and drug driving.

The driver of the Peugeot Boxer, a 50-year-old man from Bristol, was taken to Southmead Hospital in Bristol following the collision for medical treatment.

His injuries are not life threatening.

Both carriageways were closed until around 9.30pm on Wednesday night as emergency services dealt with the aftermath of the crashes and investigations were completed.

"Firstly, I would like to thank all road users who had their journey affected by yesterday's collision on the Prince of Wales Bridge, for their patience and co-operation while emergency services were in attendance carrying out essential duties at the scene," said senior investigating officer, PS Leighton Healan.

"Secondly, we are keen to speak to anyone who may have witnessed the manner of driving of the white Ford Transit van, registration number HW70NSF, in the lead up to the collision.

"If you saw anything that caused concern please get in touch."

Witnesses, or anyone with dashcam footage, is asked to telephone Gwent Police on 101, quoting reference number 2000393370.
