raf-marham-knife-isoDetectives investigating the attempted kidnap of an RAF Marham serviceman are following up more than 30 calls after a nationwide television appeal.

A reconstruction of the attack was screened on Monday night’s BBC Crimewatch which was broadcast live from the West Norfolk base.

The serviceman was jogging near the station on July 20 when two people attempted to drag him into a dark-coloured people carrier, parked on the roadside.

The attack happened around 3pm in Squires Hill. The airman managed to fight off one man and escaped when a second man, armed with a knife, went to help his accomplice.

The reconstruction showed how the  terrified airman then managed to run back to the safety of the base.

Following the programme, Detective Superintendent Paul Durham, who is leading the inquiry, said: “We’re very pleased with the initial response.” He said officers were sifting through the information and prioritising potential leads.

“There have been some names put forward and these will be investigated and cross-referenced with information we already hold,” he added.

Officers this week released a photograph of a knife (pictured) similar to the one they are looking for and also CCTV footage of vehicles in the area at the time.

A renewed appeal has been made for witnesses to come forward and Det Supt Durham said nothing had been ruled out as far as motive was concerned.
