An 18-year-old man has been arrested after a car collided with a crowd of pedestrians outside a nightclub in Wales, causing "life-changing" injuries to two women.

The teenager was arrested on suspicion of causing injury by dangerous driving after a car hit crowds in Cambrian Road, Newport, at about 5.30am on Sunday.

The vehicle, believed to be a blue Ford C-Max, collided with four people – three women and one man.

Police have reassured the public that the incident was not terror-related.

A spokeswoman for Gwent Police said all four were taken to hospital, and two of the women were believed to have suffered life-changing injuries.

"Following the incident this morning on Cambrian Road in Newport involving a car and four pedestrians, an 18-year-old man from the Newport area has been arrested on suspicion of causing injury by dangerous driving," she said.

"Investigations are ongoing and we'd like to thank everyone for their comments and shares."

Footage circulated on social media appears to show people screaming as a car hits a crowd of revellers.

The vehicle was later found burned out on Magor Street in Newport, a force spokesman said.

"I'd like to just reassure the public that this incident is not believed to be terror-related and has no links to the Newport marathon that is taking place this morning.
