A man had to be taken to hospital after receiving a serious head injury in a crash.

The man, 63, was truck by a Ford Transit van as he crossed the Derwent Road Roundabout in Colchester at around 4pm on Thursday afternoon.

The white Ford Transit van initially stopped at the scene but drove off prior to police arriving.
