South Wales Police linking two incidents on the A470
A man is in a critical condition in hospital after apparently jumping from a moving white van on the A470 near Taffs Well, north of Cardiff.
He was taken to the University Hospital of Wales, Cardiff with serious injuries.
Police were called to the area after earlier reports from people concerned for a man on a bridge at Fiddlers Elbow roundabout in Abercynon at 3.40pm.
Officers believe he left the area in a white van before they arrived.
Fifteen minutes later, he was seen jumping from a van on the A470.
Anyone who may have witnessed either incident, the manner of driving of the vehicle, or has dash cam footage should contact South Wales Police on 101 and quote Occurrence number 1900229321
