Frank Williams (at the time a detective inspector) claimed that at least three men who were directly involved are still at liberty and enjoying their full share of the money stolen and the profits from the way they invested it, one of them being the man responsible for the attack on the train driver. Williams said that the train driver's assailant was not some phantom figure lurking in the criminal underworld, and that he traced him, identified him and took him to Scotland Yard where, with Tommy Butler, Williams questioned him. He could not be charged because of lack of evidence; there were no fingerprints or identifiable marks anywhere. None of those arrested informed on this person, although it was claimed that he had completely disobeyed instructions and used violence during the robbery.
