"We don't really know what happened at the moment, but all I can say is we feel sorry for the family who have to cope with this now.

"My thoughts are with them."

Other people in the area have spoken of their sadness and shock at what happened.

Police have said they are dedicating "considerable resources" to the investigation as they revealed they had launched a murder probe.

They have set up an online information portal as part of the investigation.

The portal has been set up so people can share information with detectives from the Joint Norfolk and Suffolk Major Investigation Team who are now treating the man's death as murder.

Detective Chief Inspector Phillip Gray, who is leading the enquiry, said: "Brandon Road carries a lot of traffic and I would particularly appeal to anyone who has dash cam footage to get in touch with us.

"I also want to reassure the community that we are dedicating considerable resources into establishing exactly what happened. They will see an increased police presence in the area over the following days."
