Detectives investigating the murder of a 36-year-old man in an apparent shooting outside a travellers’ site are not expected to name the victim until after a post-mortem examination today.

Police were called to First Drove, Burwell, near Newmarket, at about 2am yesterday and found the man in the road.

A second man found at the scene with facial injuries was taken to Addenbrooke’s Hospital, Cambridge, but later released. The man was said to have suffered bruising and other minor injuries.

A team from the Bedfordshire, Cambridgeshire and Hertfordshire major crime unit has been called in to lead the investigation.

Detective Chief Inspector Jason Gordon is heading the inquiry which he says remains “in its early stages”. At the moment he says police are treating it as “an isolated incident”.

Det Ch Insp Gordon said while his team concentrated on the murder hunt, the local neighbourhood policing team would step up patrols locally to offer reassurance to residents. “We are keen to hear from anyone who may have information about this man’s death,” he said.

Forensic experts are at the scene and erected a tent over the spot where the 36 year-old victim was discovered. A detailed search of the area is being carried out. A police cordon has been set up around the area.

Anyone with information should contact the major crime unit on 101 or Crimestoppers, anonymously, on 0800 555 111.
