The occupants of three cars are still being sought by police following a fatal crash on the A140 near Norwich.

The drivers and passengers of a grey Nissan vehicle, possibly a Qashqai, a silver Citroen C1 and white Mitsubishi L200, could hold key information about a serious collision involving a black Honda motorbike and a white Vauxhall Astra.

The motorcyclist, a man in his 50s, was declared dead at the scene of the crash which happened between Horsham St Faith and Newton St Faith at 3.12pm on Sunday, March 31.

Witnesses were either spoken with at the scene or have since come forward to the investigation.

But officers still wish to hear from the drivers and occupants of the three vehicles mentioned which were all seen in the area of the collision as they were driven on the A140 towards Norwich. 

A spokesman for Norfolk Police said: "The investigation into the circumstances of the collision continues." 

Anyone with any information is asked to get in touch with Norfolk Police on 101 quoting reference 36/21554/24.
