Detectives investigating the attempted abduction of an RAF serviceman at Marham in Norfolk have released e-fit images of the suspects.
It comes as police mark the one-week anniversary of the attack.
The victim, a man in his late 20s, was out running between 2.45pm and 3.26pm last Wednesday when he was approached by two men. The victim managed to fight off his attackers, who then fled.
The suspects, both described as Middle Eastern origin in appearance, remain at large and their vehicle has not yet been located.
Suspect One is aged between 20-30, about 6ft tall, of athletic but stocky build, with dark hair which was long on top and had a well-groomed beard. He had a dark skin tone and wore causal clothing.
Suspect Two is aged between 20-30, but younger than the first suspect and of a slimmer build. He was about 5ft 10, clean shaven with short dark hair and wore a white t-shirt and dark shorts.
While the victim only witnessed two people during the incident, officers have said it is possible there was at least one other person in the vehicle.
Detective Superintendent Paul Durham is leading the Investigation with support from officers at the Metropolitan Police Counter Terrorism Command.
This afternoon police were carrying out concerted witness appeals in Marham, seeking information from people who were in the local area last Wednesday.
