Two men involved in the attempted abduction of a serviceman at RAF Marham were part of a larger team, Norfolk Police can confirm. It is believed there could have been more than two suspects inside a dark-coloured Ford Galaxy at the time of the incident on 20 July.

"This is important because I do not want to deter any potential witnesses from coming forward," said Senior investigating officer, Detective Superintendent Paul Durham. "It is the vehicle we are interested in, regardless of the number of people seen inside."

The victim was approached by two Asian males, one armed with a knife, who tried to bundle him into their vehicle while he was running outside the airbase.

Police are appealing for information from the public and motorists who were in Squires Hill when the incident occurred that afternoon around 3.30pm, especially homeowners with private CCTV.

The road has since reopened but police patrols are continuing across the weekend for public reassurance.

DS Durham added: "Another area of interest is any dash-cam footage motorists travelling in Marham or King's Lynn area may have which they think could be useful to us. Many people now use these devices and they may contain something that the driver or rider isn't aware of so I would urge people to review their footage from the week leading up to the incident and contact us if they feel it could assist the enquiry."

RAF Marham is home to four squadrons of Tornado bombers fighters, which have been used in raids against Islamic State (Isis) in Syria since December from a base in Cyprus.

One leaked memo earlier this week read: "Following a security incident at RAF Marham, it is directed that all service personnel keep a low profile and not make themselves vulnerable. Specifically, until the threat subsides, no one is to be on their own on foot, or on a bicycle, within the local area in uniform, or clothing which might identify them with the military."
