Police investigating the attempted abduction of a serviceman at RAF Marham in Norfolk have received more than 500 calls from the public.
It comes a month on since the attack which happened on Squires Hill while the serviceman, aged in his 20s, was out running.
Public appeals and the release of e-fit images of the suspects, resulted in about 550 calls from the public.
Despite a significant response from the public, there have been no confirmed sightings of the suspects who remain outstanding.
A 60-strong team of detectives, 50 from the Norfolk and Suffolk Major Investigation Team and 10 from the Metropolitan Police Service Counter Terrorism Command, are working on the case.
