A man in his 40s has died in a crash on the Northern Distributor Road just outside of Norwich.
The incident happened at around 10pm on Wednesday night on the A1270 at Horsham St Faith near the A140 slip road towards Hellesdon.
It's believed that the man, who was aged in his late 40s and was driving a blue BMW, had hit an animal, believed to be a deer, and got out of his car to inspect the damage.
He was then struck by two cars, thought to be an orange MG3 and a small silver car similar to a Peugeot 106 or Citroen C1.
Police confirmed he died at the scene.
The road was closed for several hours following the crash but reopened at about 4am.
A woman who was driving one of the cars involved in the crash has since got in touch with the police following a public appeal.
"We believe the driver of the BMW may have hit an animal and stopped on the roadside to check the damage," Inspector Chris Hinitt, from the Norfolk and Suffolk Roads and Armed Policing Team, said.
"He has then been involved in a collision with two other vehicles, one of which, the silver car, initially stopped but then left the scene."
