A man is in a critical condition after reportedly falling out of a moving van on a major link road, police have said.

Concern was raised for a man on a bridge at the Fiddler's Elbow roundabout, Abercynon, at about 15:40 BST. He left in a white van before police arrived on the scene.

Police were then called to the A470 southbound at Taff's Well following reports a man fell from a white van.

The road was closed for nearly four hours but has since reopened.

The man was taken to the University Hospital of Wales in Cardiff with serious injuries, police said.

The northbound carriageway was briefly closed between Taff's Well and Coryton interchange to allow an air ambulance to land.

South Wales Police thanked members of the public who assisted at the scene and appealed for witnesses or dash cam footage of either of the two incidents.
