Peter Robbins has reveiled that he now believes that the former US airman Larry Warren's account of what happened during the incident near RAF Bentwaters, Suffolk in 1980 was "not true".
Mr Robbins and Mr. Warren, co-author's and one-time friends are in conflict over the account of the famous Rendlesham Forest incident. They co-authored 'Left at East Gate: A First-Hand Account of the Bentwater-Woodbridge UFO Incident, its Cover-Up, and Investigation'.
The feud didn't stop between them, Warren pulled Nick Pope into the feud by blasting Mr. Pope on Facebook, calling him a liar.
Speaking on the Inception Radio Network, Robbins said: "Over the past year, even a bit more, highly specific information has been brought to my attention that has disturbed me tremendously".
