Police have received more than 100 calls after e-fits of two men involved in the attempted abduction of a serviceman at RAF Marham.
150 calls have been made to a dedicated hotline set up following the incident last Wednesday afternoon.
The victim, a man in his late 20s, was out running between 2.45pm and 3.26pm when he was approached by two men. The victim managed to fight off his attackers, who then fled.
The suspects are both described as Middle Eastern origin in appearance.
Officers are continuing to carry out enquiries in the area and nearby village.
